Summer and winter
That is interesting
.very nice explanation thamku sir ❤❤❤❤
Glad to see the comment
Well explained 💯
Glad to see the comment.
America is in the West and Singapore is in the East. Therefore at 12.00 GMT the sun rises in the West (6.00 GMT) and sets in the East (18.00 GMT).
Confusing statements...
@@ScienceforCommonman It is NOT the statement that is cofusing, but the totally inconsistent use of terminology. And scientists call their system most precise, accurate and internally CONSISTENT. Try also to find the PHYSICAL MEANING of the 3 positive and 3 negative directions of the Cartesian system of coordinates (why should East, North and Midday directions be called positive and the corresponding other 3 negative, if one applies it to the Center of the earth?), much worse even, what PHYSICAL MEANING can one associate with calling proton positive and elactron negative? The only property of any particle, viz. its volume (= size) is already assigned to its MASS.
best explanation sir
Glad to see the comment
What causes light to bounce in the water droplet & not pass through? Although some light must be made through the droplet what makes this so? How does the light escape the droplet what factors cause this? Even with the other videos I still have a hard time understanding. Shouldn't we see a micro rainbow full circle infront of a viewer, if that viewer is directly surrounded with suspended water & white light from the Sun from all directions?
Whenever light reach a new medium, some of it may reflect, while some if it may pass through. This happens at every boundary with the water, but obviously the other light is lost in other directions which our eye doesn't see.
"Shouldn't we see a micro rainbow full circle infront of a viewer" If you were to draw out all the lightrays from the sun, it would look like a complete mess with light bouncing everywhere (we're talking light being reflected/transmitted at/through at every surface in every raindrop, as well as incident light hitting all different points of the raindrops). Luckily, you only need to consider the light that actually makes it to your eye, so you can disregard pretty much all of this. If you were to do this, you would clearly see why the rainbow shape appears. You're right in that raindrops close to our eyes also reflect "rainbow-light" into our eyes, which increases the perceived intensity. The rainbow appearing "at a distance" is of course an illusion, and all raindrops at the right angle, stretching far into a distance, will reflect some of the light into your eye.
Great thinking to have these questions. Will answer one by one. 1. What causes some of the light to bounce and some to pass through? To answer this, we need to consider quantum behaviour of light and the answer is probability. To further understand this, I would recommend you to read Richard Feynman's "QED: The Strange Theory of Light and Matter" (Quantum Electro Dynamics) 2. Micro rainbow formation... This could be theoretically possible. But the intensity of those coloured light, compared to the ambient light would be so less. The intensity depends on number of drops lined up for producing a particular colour in the cone. Hope this helps.

Thank you so much. you are the only person
Glad to see the comment
Have you made a video for a double rainbow?
So far no..
Very well explained. Very much appreciated. I am grateful for your work
That is an encouraging comment too...
Very nice explanation ever seen ❤
Glad you liked it
WHAT RAINBOW'S ARE CIRCIE'S WHAT nae man NAEEE
Ok
Very good explanation. The only thing you might add is why you can see the full or new moon without there being an eclipse. You could do that by rotating your animation so that we could see the moon is either slightly above or below the straight line between the sun and d earth.
Glad to read the comments and Many thanks for the suggestions

Great bro
Thank you so much 😀
Awesome video. Keep up the great work. I'm a common man, so really appreciate your content. One thing I disagree with - the Sun won't become a red giant before the Earth and Moon tidally lock. It will if we don't do anything. But we will prevent it.
Glad to read the comment. Let us agree to disagree on the second part of the comment.
Outstanding explanation.
That is a nice comment too..
Nice explanation 😊sir

You are Welcome
I'm watching this vid to understand something our doctor said about transparency of cornea of eye. He said that the distance between the arranged fibers is less than wavelength of light. What can that mean in the eye of physics?
In the language of physics, an object becomes transparent when there is no mechanism in the material to absorb/scatter the photons in the visible light. Cornea becomes transparent as it is made up of molecules which cannot absorb/scatter visible light. The energy levels of electrons in such molecules are much higher than available in the visible light. If a fibrous material, capable of absorbing photons are distributed densely and closely in the cornea, that can affect passing of light and transparency. The Doctor could have been mentioning this aspect.

Thanks a lot!@@ScienceforCommonman
you are the best! Great explanation
Thankyou for the feedback
You explained very well. well done my friend 👌🏻👌🏻

Hello friend, thank you so much for this clarification! I'm very glad you made this video, the only regret I have is not taking psychedelics before watching. Have a colorful day!

Hindi bhasi kaise samjhe.
Please change the subtitles language to Hindi
despite that, there is vastly more empty space between the molecules too, which should have allowed majority of the light to pass through to make almost everything transparent. why does it not happen?
That is an interesting question. The size of atoms are infact very very small. They are around 100 picometers. A sheet of one micrometer thickness may have 10000 layers of atoms stacked up. So, there are sufficient layers of atoms even in the smallest possible thickness... In spite of this, everything becomes transparent when the thickness is too low, of the order of picometers or nanometres...

Best explanation sir , Can we plant bird eye instead human eye?
Technically, it should be possible. But, we should train our brain also according to that .
Sir ji , jis tarah species ke colour ka bhram hai usi tarah swad , gandh, avaj aur आकार के साथ भी होता है क्या ? ज्ञानेंद्रियों के साथ ? या फिर सायद आकार में न हो बाकी 4 में हो ? Sir ji , Please reply me
Yes. Regardin sound, the frequency and loudness, the different species can sense are different, based on the difference in sensors they possess.
