What does it mean to polarize light?

Causes light to travel in only one plane

When red light is compared with violet light,

red light travels faster than violet light.

The farther light is from a source,

the more spread out light becomes.

the more condensed light becomes.

the more light is available per unit area.

is produced by real rays and can be projected on a screen

is produced by virtual rays and can be projected on a screen

is produced by real rays and cannot be projected on a screen

is produced by virtual images and cannot be projected on a screen

What happens when an object absorbs electromagnetic waves?

It causes it to become transparent

What do the most energetic electromagnetic waves possess?

short wavelengths and high frequencies

long wavelengths and low frequencies

long wavelengths and high frequencies

short wavelengths and low frequencies

because nitrogen and oxygen molecules scatter blue light more than the other colors

because the atmosphere absorbs blue light and reflects the other colors

because the ocean reflects its blue color to the sky

because nitrogen and oxygen molecules scatter red and oranges away during the sunrise leaving blue for the day time

According to the Law of reflection, a light ray striking a mirror

bounces off the mirror at the same angle it hits.

continues moving through the mirror in the same direction

moves into the mirror at a slightly different angle

bounces off the mirror toward the direction it came from

For a beam of light, the direction of polarization is defined as

the direction of the electric field's vibration.

the beam's direction of travel.

the direction of the magnetic field's vibration.

the direction that is perpendicular to both the electric and magnetic field vectors.
