Polarization of Light

What is the difference between light that is polarized and light that is not?

• polarized light vibrates along multiple planes; unpolarized light vibrates along a single plane

• there is no difference

• polarized light vibrates along a single plane; unpolarized light vibrates along multiple planes

• True

• False

Why is light from a lamp or candle frame nonpolarized?

• The electrons are vibrating in one direction

• The electrons are vibrating in random directions

• The electrons are not moving

• They emit polarized light

What is the primary effect of a polarizing filter on light?

• It increases the intensity of light

• It changes the color of light

• It aligns the light waves to a single plane

• It scatters the light in all directions

How does polarized light differ from unpolarized light in terms of wave orientation?

• Polarized light waves are oriented in multiple directions

• Polarized light waves are oriented in a single direction

• Unpolarized light waves are oriented in a single direction

• Both have waves oriented in a single direction

What happens to light when it passes through a polarizing filter?

• It becomes brighter

• It becomes polarized

• It changes color

• It becomes unpolarized
