Fyi...I think the drawing of the polarizer in the diagram at 4:44 in the video should be turned 90 degrees. To me, it looks like the wave that made it through should have been blocked and the horizontal wave that was blocked should have made it through. Your thoughts?
Can you answer me this problem please If the time of 0.5 amplitude is 2 second calculate the time of complete oscillation or vibrating Reply quickly I'm intersted
There isn't enough information, because we don't know the wave shape in this example. We also don't know the starting phase in the cycle, or which of the half-amplitude points we are given, within the cycle. Assuming it is sinusoidal, and that it starts in the phase of a sine wave, the half-amplitude occurs whenever sin(theta) = 0.5, and the full cycle occurs for every time theta equals an integer multiple of 360 degrees. When does sin(theta) = 0.5? The first answer is theta = 30 degrees, and the next answer is theta = 150 degrees. The general answer is 90 deg +/- 60 deg + n*360 deg. Most likely, the problem author had the first answer in mind, as the given half-amplitude point. This means it takes 1/12 of a cycle to move from the equilibrium state to the half-amplitude state, and therefore, the period of a full oscillation is 12*2 sec = 24 seconds.
Yeah, a wave from my understanding is what something does and you can't have a wave without something moving. If light is a wave then that means all around us is a medium that we're not aware of that allows electromagnetic waves exist.
But if you go out in space where the medium is not thick enough (low density) you are not going to see any explosion from a nova, you wont even see the stars!
Any proof of your statement that emf waves does not need a medium? Have you tested that in some way or is it just a religion of yours and "The cult of Physics"...
The fact that you can see the sun, is proof that an electromagnetic wave doesn't require a medium. If EM waves couldn't travel through empty space, you wouldn't ever see any astronomical body, and the sky would be pitch black all the time.
A wave whose disturbance of the medium is is parallel and anti-parallel to the direction of propagation, rather than a wave whose disturbance of the medium is perpendicular. An example of a longitudinal wave, is sound.

who else has to watch this for school
BRUH HAHAHAHHAHAHAHA OMG HBDBCB
Broooo meeeee
everyone did dumbass
@@hila404 same🤣🤣
the shoulder dance at 4:43 is where its at
Nice catch. That is weird.
ahaha
lol
@@Bozemanscience1 nah it's a happy science wiggle, perfectly normal
if you ever feel smart, study physics
Everyone is smart!!

Thx for the A on my test
Thanks for the video. I have a pretest in science about this soon and now I'm gonna do great on it.
wgu?
I will give three goats for this work because you have helped me
thanks sir its really help me to know waves better in easiest way
shoutout to ms conradie
Wow wonderful. Those animations really helped. Thank you so much!
Superb animated video
this is sooooooo helpful and easy to understand!!!!!!!!!!!!!!!!!!!!!!!!!!!!
good work buddy, helped a lot.
awesome cool explanation. Thanks
excellent work.

Great work😃
See this video is better than reading my theoretical book covered with sums and this is for school.
i think transverse waves are not really up and down but in reality more circular...swinging in a circular spiral movement.
thank you, grate explanation.
Sound will be heard from space huygen said there is a medium called ether which travel in sound waves and light
Yeah, a wave from my understanding is what something does and you can't have a wave without something moving. If light is a wave then that means all around us is a medium that we're not aware of that allows electromagnetic waves exist.
How does a low-frequency mechanical (transverse) wave behave in a plasma ?

perfect
this is coming from a man who lacks in grades a little bit. But thank you so much for your educational videos!
Thanks! Was very helpful :)
Great video!
I love you sir
Love your videoes!
thought we already did this the last two terms
Hi Mr Andersen, just wondering what program do you use to create your videos?
Thank you :)
+Steph You can use Adobe After Effects or Sony Vegas.
thank you
You spelled longitudinal waves wrong in the title slide
great vid was really helpful :)
Nice one
EMF also requires a medium otherwise it can´t oscillate! Prove that I´m wrong...
My boi weez x is going to live stream today guys
THE GOAT
thanks sir
very helpful thx
But if you go out in space where the medium is not thick enough (low density) you are not going to see any explosion from a nova, you wont even see the stars!
I don't get a WORD!
thanks finally understood it
Sir bozy the gr8 bossssie
thanks
This is AP physics 2! I needed to know this and I'm in 7th grade!
You have physics in 7th grade...
interesting.
Hi
Brayden Hosford hey Brayden
Evan Ankrum hey daddy
Ms Colman is so hot
Evan Ankrum I agree
I am not getting longitudinal waves but I got transverse waves
👍👍

Who is watching this in the carona season
Have you ever been so smart that you miss spell longitudinal ( the beginning)
WHAT THE FUCK IS A LONJITUDINAL WAVE
A wave whose disturbance of the medium is is parallel and anti-parallel to the direction of propagation, rather than a wave whose disturbance of the medium is perpendicular. An example of a longitudinal wave, is sound.
what
1:59 in my room... okayy buddy im being forced to watch this boring video #badlol
lol atleast his teaching is wayy better than half of the physics teachers we have 9 yr old.
Great. Except the earth is flat and electromagnetic waves certainly need a medium to go through like all waves, it's called the aether.
Both of those are obsolete ideas.
