When taking a picture of a highly reflecting surface,it is desirable to use a polarizer in front of the camera to cut down on the "glare".Suppose you are taking a picture of a lake where the water is very still.The polarizing axis of the polarizer should ideally be oriented
A)horizontally.
B)vertically.
C)at 30 $\circ$ .
D)at 45 $\circ$ .
E)in any direction.

When taking a picture of a highly reflecting surface, such as still water, the polarizing axis of the polarizer should ideally be oriented vertically to cut down on glare and reflections. This is because the light waves reflecting off the surface of the water are predominantly oscillating horizontally, which can be blocked by a polarizer with its axis oriented vertically. Choosing any other orientation, such as horizontally or at an angle, may not be as effective in reducing glare from highly reflective surfaces. Thus, choice B is the best choice.
