chapter 11 review

The black fur of a black-and-white bunny is due to light

absorption

If an electric charge is rapidly shaken up and down,

an electromagnetic wave is produced.

When visible light is incident upon transparent glass, most atoms in the glass

are forced into vibration

The direction of vibration for an electron and the plane of polarization of the light it emits

are the same

The different colors of the spectrum

blend from one to another

Refraction occurs when light passing from one medium to another

change speed

The white light from the Sun is a

composite of light of all the visible frequencies

The source of electromagnetic waves is vibrating

electric charges

Most of the waves in the electromagnetic spectrum are

invisible

Relative to its average speed in air, the average speed of a beam of light in glass is

less

According to the law of reflection, the incident ray, reflected ray, and normal between them

lie in the same place

A changing electric field induces a changing

magnetic field

Electromagnetic waves consist of

oscillating electric and magnetic fields

Visible light that shines on a pane of transparent glass

produces a chain of absorptions and re-emissions through the glass.

When ultraviolet light is incident upon glass, most atoms in the glass

resonate

When light from air passes through a prism, light of all frequencies

slow down

When light from the air enters a raindrop, the light

slows down

The color of an object depends on the colors of

the light that illuminates them

consider light energy that is momentarily absorbed in glass and then reemitted. Relative to the absorbed light, the frequency of the reemitted light is

the same

Non-reflected ultraviolet light that shines on a pane of transparent glass

transforms to thermal energy

Polarization is a property of

transverse waves

Electrons in glass have a natural frequency in the

ultraviolet region of the spectrum

Which of these has a higher frequency than visible light?

ultraviolet wave

Which of the following occupies the smallest percentage of the electromagnetic spectrum?

visible light
