Light Dispersion and refraction through prism.
Have you ever noticed that diamonds sparkle in sunlight? Ever wondered why?
They sparkle and give seem to be giving out different colors.
Just like oil spilt on any surface showcases different colors.
The reason behind these phenomena is the diffraction of light.
Before we understand what refraction is let us conduct this easy and cool experiment of extracting a rainbow from white light
For this experiment, you'll need
• Prism
• White light
• And a dark room where the refraction can be clearly seen.
Procedure:
• Take the prism and keep it on the table.
• Ensure that the room is considerable dark for this light to be obvious.
• When light travels through the prism, it splits the white light in to 7 colors. These are Violet, Indigo, Blue, Green Yellow Orange and Red. They appear in the same order , just like in the rainbow.
• Observe the light ray carefully inside the prism. Notice that the light ray bends at two different points - one when the light is entering the prism and another when it leaves the prism.
Question is -why is the light being dispersed into the rainbow colors?
Explanation:
Prism is made up of glass. The seven different colors coming out of the prism constitute seven different wavelengths. Each color represents a different wavelength of light. These different wavelengths travel at different speeds in glass. This is the main reason for the formation of rainbow or spectrum when the light travels through the prism. Another point to be noted here is that the angle of refraction is different for these colors as they have different wavelength.
When light touches the surface of the prism, refraction takes place at the boundary of the prism i.e. boundary between air and glass. Then e white light is separated into its component colors - red, orange, yellow, green, blue and violet.
Refraction is the change in direction of a wave due to a change in its medium.
When these wavelengths reach the other side of the prism at different angles, refraction takes place at the surface of the prism i.e. at the boundary of the glass and prism and the angle of refraction is greater when they leave the prism.
This separation of visible light into its different colors is known as dispersion. All these colors constitute the spectrum.
The angle of refraction which a light undergoes when it travels from one medium to another medium is determined by the refractive index of the given medium.
This is the reason why the diamond sparkles in broad daylight and makes it shiny.
Thank you for watching and don't forget to subscribe
At 2:04 the colors are backwards, the violet light should be on the bottom because ultraviolet light refracts the most, and red doesn't refract enough to bend like it is in the video
There are only 6 colours, Isaac Newton found six colours, but he was very religious and the number six is the devil, so he added indigo and that made 7 one of the bibles lucky numbers. I know I'm only 13 but I learnt that from top set science :) hope this helps
I DONT THINK SO!!
actually indigo is visible but you need to look closely between the blue and violet. Its very subtle.
Who else here for school? I have to do a video type web-quest on light and colors this helped a lot.
same
MY teacher set this for homeschooling if you didn't have a prism and it really showed me how the experiment would have worked if I did have a prism! Thank you so much. xx
This is a very good way of learning about refraction thank you for all your help
+Nova Genesis HE misses some stuff out
In 2:04 and 3:10, the graphics are wrong.
How does a medium enable the constituent colours to split ?what property is it? Why white light does not travel as a spectrum in vacuum?
The medium allows light to split because the medium has electron orbitals that directly interact with light, allowing certain colors to move at different speeds. This is a quantum mechanical effect of an electron orbital, meaning you need both an electron domain and a nucleon to demonstrate this effect.
White light does move as a spectrum in a vacuum, but the spectrum cannot be split up and observed. To observe it would require the existence of something which is counter to the existence of a vacuum (for the record, air is not a vacuum).
Thanks my mum didnt understand this so I explained it
Ahh so thats how you make Dark Side Of The Moon
Why light not dispersed in the glass cube???????..….
Wow so nice soo nice
Great vid! Especially liked the direct observation of Dispersion at 1:17. However, your animation at 2:02 is flipped! You have the red light bending more than the violet light. With the higher frequency of blue light, it should bend more, and vice versa, the red light should bend less.
they weren't very careful with their graphics. Consider the graphics between 2:04 and 3:10 and see if you can see what's wrong with the colors. Can you see it?
Green is barely visible but I think it's there, also indigo and violet are pink
Wendee Byrne violet should be the most deviated and red the least that is, red must be at the top rather it is shown at the bottom
bruh my school really just copy-pasted your comment
@@asappyghost232 same lmao
The question is why is the "original" white light "SOURCE" actually several colors combined into one? Ask the right question to achieve the right answer. The light source is the Sun which is like the Moon. Two lights created as the bible says above the firmament of earth of which the sun and moon are luminary as there is water above and below the firmament of earth. Sounds are Frequencies as Sonolumenesence proofs how the stars above were formed. Each color has a sound frequency as well. It's all in the Bible of which man refutes but in the end always comes back to for UNDERSTANDING!
Who else is here for homework
Not me
2:02 The light refraction here is flipped. The light with higher wavelength refract more than light with lower wavelength.
They really expect us to just have a diamond laying around in our house.
Nice it really help out my science report about Refraction
The video really helped me!!!👍👍👍
It was great
Dude, you got the colours of the rainbow upside-down, it's the other way around! /:l
doesn't matter
Captain Origami it's seen from the bottom dude -_-
rekha swamy if it was seen from bottom then the incident ray would travel downward not upwards.
Red light bends the least.
that's pretty lit dude
crazy innit
@@toiletcrew9025 hell yeah
Hi, thanks for the video!
Where did you get that white light source? I'd love to get my hands on one to conduct this experiment!
he used the flash light from a phone
SERIOUSLY .....................?? HE GOT THE WHITE FROM ALIENS WHO WERE FRM OTHER GALAXIES...........
@@sohanchowdhury1312 the vidio sucks
thank you you helped me with my assignment i had to try and make a rainbow using a glass prism
now i can start my paper thanks .
I also can do my homework
awesome vid! great work, loved the music.
the vid sucks
what happens when instead of white light red light is incident on prism plz tell soon Tom. I have exam
Chetan Valera only red light passes
Hope you did well on your exam, although that was four years ago 😅
brothers, i just wanted to know why the refraction occurs.
does the refractive index of glass different for different colors and etc.
so please help me out.
i wrote an exam last week and there were 4 prism. The first and the fourth "stood" like your prism in the video, but the second and third prism are standing on their corner. We should have shown how red and violett light would travel through them... so how do they it?
Nice video but the floating watermark is incredible distracting.
What is the action of white light passing through a prism and indicate the colors of light.
your colors from the prism are upsidedown
This can actually b applied to the dome that covers the earth n the nothern lights...quite interesting!
I hear ya. plus.google.com/116502556172406985386/posts/MBzwpYLN69f
Wow nice vido
Well done
wow wonderufl
where did you get a prism
yh
+Connie Zhang GO TO A SCIENCE LAB OR CLASSROOM AND ASK THE SCINCE TEACHER
Or you can just buy it on amazon.
1) You did the experiment wrong
2) You did not say light spectrum as that is a key word to remember
3) You did not explain on how red has the longest wavelength and violet has the shortest wavelength
4) You did not mention that violet is refracted more that red due to the wavelength
HOPE THAT HELPS
How old are you? (just wondering)
+Harshi Shah dont cry
+Jack Swagger how did you know I was crying right now
Why does hollow prism will not produce any spectrum
Its so good
Where do you get prism
Bruh what WAS 2013? Same with 2015, 2018, and 2020
it has just 3 color, red, green and blue. When the green color touch to the red, is giving yellow. Cause of, just 3 color are visible on black surface, but never seen to the yellow on black surface, yellow is visible on green or red surface.
Those three are only the colors your eye's retina reacts to, but that's irrelevant to the actual physical phenomena which consists of an unmeasurable number of wavelengths, not a mere 7.
Nice video! At 2min02, colors are inverted.
Im gonna go spill some oil now!
Wow.......
+rahul prajapato he did not do the experiment properly
@@zorossenseofdirection2698 how
nice
Red color which is the least deviated should be up not down ,I think that the colors are wrongly inverted
Magid Awad that's why animations is not really good in explaining science, and should not replace real experiment.
HAMDANI YUSUF was
The rainbow is backwards. Violet should have bent the most not red.
refraction fragmentation vibe emotion love hate scared EM=WAVE DISPERSION CREATION
okay call me crazy but doesnt the refractions resemble the universe at 0:09 secs.
hugh mann which part of the universe?
nice video but between 2:04 and 3:10 the colors are flipped. Violet should be at the bottom because it bends the most not red. Red should be at the top because it bends the least.
it honestly doesn't matter stop being weird
Ha my teacher told me to comment that because she saw it and said the we should all commit at it 😁
The colour of the rainbow is flipped at 2:04. Otherwise good video!
flip da rainbow
Anyone else get this video for school
That poor scientist had to relive dyeing several times.
Can you make it more so that it looks like the cover of pink floyd dark side of the moon album
what is this?
...
Just to let you know the rainbow is upside down
How is the light making a rainbow?
they didnt even do the experiment yall
order of colours in the video is wrong
no
What's the name of the music?
Me listening to pink Floyd:
the rainbow is reversed at 2:04 to 3:10 lol
MINECRAFT FORTNITE ROBLOX APEX LEDGENDS PUBG MARIO KIRBY UNDERTALE
Omg I’m sooo confused 😅
music......??????
what really pisses me off in these videos is that none of the people doing the experiments fully understand physics. not all mediums do this effect!! don't think that you can buy a plastic prism and go ahead. water doesn't exactly do this effect but you could assume it is an "infinite liquid prism"
you got the colours backwards 1v1 me minecraft dog water box you like a fish
yes lad
Have you ever seen a diamond?
me: bro.
refractions starts when light enters the prism

they forgot about the green.
i love the part where you gave me robux
nerd!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Between 2:04 and 3:10 when they were showing the refraction, the rainbow only had six colours because they forgot GREEN! In this it goes Red, Orange, Yellow, Blue, Indigo and Violet! CHECK YOUR GRAPHICS! And purple and indigo are pink. This bothers me...
it doesn't matter werido
Indigo.......... you don't belong on there as a separate colour! go home indigo! you're drunk! >:(
Lol

they weren't very careful with their graphics. Consider the graphics between 2:04 and 3:10 and see if you can see what's wrong with the colors. Can you see it?
Is it the fact that it was not in the middle, my online teacher mentioned the exact same thing
Lol
