Why do you see a red sunset sometimes?

AI Thread Summary
A red sunset occurs when clouds or high levels of water vapor scatter shorter wavelengths of light, allowing primarily red light to reach the observer's eyes. This phenomenon is enhanced by atmospheric conditions that filter out other colors. The discussion also briefly touches on the formation of rainbows, which is linked to light refraction and dispersion through water droplets. The original poster is seeking clarification on these physics concepts. Understanding these principles can enhance comprehension of atmospheric optics.

Hai people, our physics teacher has given us two theory problems to sloves which I am having trouble doing, so any help on this would be great

the two problems are,

Why do you see a red sunset sometimes?

and

how do rainbows form?

any help would be great as I said

Why do you see a red sunset sometimes?

If there are clouds or even a lot of water vapor, only red light, having the shortest wave length, will get through to your eye without being scattered.

how do rainbows form?
See my answer to BryceG's "questions".
 
thanks man

and no I am not related to BryceG
 
That was a facetious question. In case you didn't notice, BryceG gave a series of questions very similar to yours.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
