Greater than the critical angle, right? That is what I'm getting but this problem is confusing. I must be doing something wrong.

A mixture of red and violet light is incident on a glass-air interface. The indices of refraction for red and violet light in glass are n(red)=1.52 and n(violet)=1.538. What color of light enters the air? http://www.webassign.net/cj8/q_10.gif attempt to solve: I found that the critical angle...

Well its KE is decreasing because the force exerted by the field contributes to its forward acceleration...

Homework Statement A proton is released from rest at point A in a constant electric field and accelerates to point B (see part a of the drawing). An electron is released from rest at point B and accelerates to point A (see part b of the drawing). How does the change in the proton's electric...

Most of my confusion comes from trying to match my logic with that of my textbook's solution. Here's what they said: At the instant the top block is removed, the total mechanical energy of the remaining system is all elastic potential energy and is 12 kA2 (see Equation 10.13), where A is the...

That is the maximum distance from which the spring may stretch to from equilibrium? Or can this also be referred to as the distance you pull it by? So if the rotational kinetic energy is never zero, is its moment of inertia always constant?

physical pendulum--thin rod Why do you have to divide the length L by 2 in these cases? The explanation that's provided in my book says "the distance L between the pivot and the center of gravity is .5 the length L." This makes no sense whatsoever. The length should be the same regardless of...

Homework Statement A block is attached to a horizontal spring. On top of this block rests another block. The two-block system slides back and forth in simple harmonic motion on a frictionless horizontal surface. At one extreme end of the oscillation cycle, where the blocks come to a momentary...
