AI Thread Summary

Unpolarised light transitioning from air to water involves a change in refractive index, affecting the speed of light. The relationship between angles of incidence and refraction is described by Snell's Law, which states n1/n2 = (sinθ2)/(sinθ1). The discussion highlights confusion regarding the correct answer to a related problem, specifically identifying answer B. The concept of moving from a lower to a higher refractive index indicates that light slows down as it enters water. Understanding Brewster's angle is essential for grasping the behavior of light at the water's surface.

Homework Statement

Homework Equations

n1/n2 = (sinθ2)/(sinθ1) = v2/v1

The Attempt at a Solution

Moving from a lower refractive index to a higher refractive index. ( Lower density to higher density means faster speed to slower speed)

The answer is answer B, I don't understand why.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
