AI Thread Summary
The discussion revolves around the need for resources to practice three key physics equations related to light and refraction. Users suggest that while the textbook may not be helpful, solving problems provided within it can effectively test understanding. Additional online resources are recommended for further practice, particularly for Snell's Law. Various educational websites are mentioned as potential sources for practice problems and explanations. Utilizing these resources can enhance mastery of the equations before the upcoming test.

Having a test tomorrow, and we are suppose to have these three equations down.

Is there any sites where I can test my knowledge of these equations, cause I have no way to see if I have it down or not, since my textbook isn't that helpful.

I just need a site that gives me all these questions regarding the three equations!

Any help would be appreciated!

I assume that there are problems in your textbook. While the text may not be much help, the problems in it are probably the best way to test your mastery of these three equations. Solve some of the problems with answers in the back that involve these equations. If you get them right, you should be good. If you get them wrong, you can see where you are still weak.
 
It looks like one is describing Snell's Law, which one could find online, but I am not sure about homework problems.

Here is an explanation -

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 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
