Angle of incidence, reflection, and refraction

AI Thread Summary
The discussion clarifies the differences between the angle of incidence, reflection, and refraction when light interacts with two parallel surfaces. The angle of incidence refers to the angle at which light strikes a surface, while reflection is the bouncing back of light, and refraction is the bending of light as it passes through different media. The phrase "light is incident on film" indicates that light is encountering the film, without specifying direction, which is defined by the angle of incidence. Understanding these concepts is crucial for solving related physics problems. The thread emphasizes the importance of distinguishing between these terms for clarity in physics.

Homework Statement



What are the difference among angle of incidence, reflection, and refraction when light strikes two parallel surfaces?

What does it mean "light is incident on film"?-is that the angle of incidence?



The Attempt at a Solution



I know how to find all of them, but I think I should know the difference-especially when they only ask for one. Thanks!

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...
