AP Physics: Reflection

Which is not evidence that light is a wave?

• It forms standing waves in microwaves.

• Its' speed depends only on its medium.

• It can be polarized when it passes through a filter.

• It reflects off opaque objects.

Which of the following has the largest wavelength?

• green light

• red light

• ultraviolet light

• microwaves

Which of the following has the largest energy?

• xrays

• UV rays

• gamma rays

• visible light

A wave that has high energy must also have a _________ wavelength and _______ frequency.

• short, high

• short, low

• long, high

• long, low

In a vacuum, which light will travel the fastest?

• blue

• ultraviolet

• xrays

• same speed

Unpolarized light is incident upon a horizontal table. After its reflection, the light will be

• vertically polarized

• horizontally polarized

• unpolarized

Unpolarized light travels first through a horizontal filter and then a vertical one. After the second polarizer,

• the light will be vertically polarized

• the light will be horizontally polarized

• the light will be unpolarized

• there will be no light intensity
