A ray of light strikes a square glass block at an angle of 45 degrees and enters the glass. If this block is surrounded by air (n=1), what is the minimum value of the refractive index of the glass if the total internal reflection occurs at point P. (see attached diagram) I'm really lost on...

Thanks! That made sense when you broke it down like that.

If I stand between two plane mirrors on opposite walls in a room, I observe multiple images. When I stand 5 m from the mirror on the left wall, and 10 m from the mirror on the right wall, what are the distances (in meters) from me to the first three images seen in the mirror on the LEFT? I...

If I have a top view of two circular coils of conducting wire lying on a flat surface, what is the direciton of induced current that appears in the smaller coil when the switch in the larger coil is closed? I'm trying to figure out: 1.) which direction the induced current would flow through...

Oh sorry! I just saw your answer. Thanks for your help!

In the problem, I wasn't given any values to plug into the formula F=qv x B. It just asks which direction the force would be going, not the magnitude. It's a big picture kind of question, which is my weak point. I'm better with values and solving equations. The question asks: If there were...

I've attached the image here. Thanks!

I've tried to find this repeatedly in my textbook, but my teacher told us to ignore the book and then didn't do a great job explaining it, but here goes... A conventional current is flowing into the page (-Z direction) along a straight wire placed at the origin O perpendicular to the page...
