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...
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...
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 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...
