What is one difference between an electromagnetic wave and a mechanical wave?
A
An electromagnetic wave can travel through a vacuum. A mechanical wave must have a medium to travel through.
B
An electromagnetic wave moves parallel to the direction of the wave's travel. A mechanical wave can move only perpendicular to the direction of the wave's travel.
C
An electromagnetic wave moves perpendicular to the direction of the wave's travel. A mechanical wave can move only parallel to the direction of the wave's travel.
D
A mechanical wave can travel through a vacuum. An electromagnetic wave must have a medium to travel through.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
