When a light ray passes from zircon (n = 1.923) into fluoride (n = 1.434) at an angle of 30°, its path is Not bent
Bent away from the normal
Bent toward the normal
Parallel to the normal

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
