Unit 12 Test - Diffraction

Front

When a wave passes through an opening, some of the wave is bent. This phenomenon is called

Back

diffraction

Front

FM radio waves are not received as well as AM radio waves in mountain canyons because AM waves

Back

have a longer wavelength.

Front

Constructive interference occurs when: the crest of one wave meets the trough of another wave., two waves of the same color overlap., the crests of two waves overlap.

Back

the crests of two waves overlap.

Front

Destructive interference occurs when

Back

the crest of one wave meets the trough of another wave.

Front

When many different rays of light all have the same frequency, direction and phase, they are called

Back

coherent rays

Front

Holograms exist because of: diffraction, interference, or All of the above?

Back

All of the above

Front

What is incoherent light?

Back

light that has many frequencies and wavelengths

Front

Which are the three ways light waves can bend? Options: Diffraction, Refraction, Reflection, Diffraction, Refraction, Transmission, Refraction, Reflection, Transmission

Back

Diffraction, Refraction, Reflection
