How is a light wave different from all mechanical waves?

Light does not need a medium to travel

What is being transferred with a wave?

Energy

____ is the number of vibrations that occur per second.

Frequency

A wave that has compressions and rarefactions is what kind of wave?

Longitudinal

If a wave goes around something that gets in the way, is that reflection, diffraction, or refraction?

diffraction

Through which state of matter do sound waves travel the fastest?

solid

If a wave bends because the speed of the wave changes, is that reflection, diffraction, or refraction?

refraction

Why can't you hear sound in space?

There is no air in space for sound to travel through (no medium)

What is the lowest point of a wave called?

trough

_____ is how far the wave travels from the rest position.

amplitude

What color do we see if all light is reflected?

white

Increasing the amplitude means you are increasing the _____ of a wave.

energy

A wave that has crests and troughs is what kind of wave?

Transverse

____ describes what you actually hear?

loudness

What is the unit for frequency?

Hertz

Which type of wave does not need a medium to travel through?

electromagnetic

If a wave bounces off a surface, is it reflection, diffraction, or refraction?

reflection

_____ is the distance between crest and crest OR trough to trough.

Wavelength

What type of light passes through a prism and refracts into different colors?

white light

What is the highest point of a wave called?

Crest

Which travels faster: light or sound?

light

Waves that need a medium are called ____.

Mechanical

The amount of energy found in a _____ wave can be found by comparing the size of the compression and rarefaction.

longitudinal

What causes the refraction of a wave?

density of the medium changing
