even more waves
100
This type of wave needs a medium
mechanical wave
100

These type of waves do NOT need a medium to travel through.

What is E.M. (electromagnetic) waves.

100
This is the speed at which a wave is moving
What is wave speed
100
This is where the particles of a longitudinal wave are crowded together
What is compression
100
This is the bouncing back of rays of light, sound or heat
What is reflection
200
X-rays and microwaves are examples of these types of waves
What is electromagnetic
200
this is any substance through which a wave can travel
What is a medium
200
This is The distance from crest to crest, or from trough to trough
What is wavelength
200
this is where the particles of a longitudinal wave are spread apart
What is rarefaction
200

This is the bending of a wave as it passes between two substances

What is refraction

300
This is any disturbance that transmits energy through matter or empty space
What is a wave
300
This is the highest point of a transverse wave
What is a crest
300
This is the number of waves produced in a certain amount of time
What is frequency
300
These are the two main types of waves
What is transverse and longitudinal
300

What would you see if you increased the amplitude of a light wave?

It would get brighter.

400

What would you hear if you increased the wavelength of a sound wave?

Low/Lower Pitch

400
This is the lowest point of a transverse wave
What is a trough
400
This is the maximum distance the particles of a wave vibrate from resting position
What is amplitude
400
Sound waves are examples of what type of wave?
What is mechanical or longitudinal
400

What would you hear if you increased the amplitude of a sound wave?

The volume would increase (it would get louder)

500
light waves are examples of what type of wave?
What is transverse or electromagnetic
500

Part of a longitudinal wave where molecules are clustered?

Compression

500
If you increase the wavelength, what happens to the frequency?
What is it decreases
500

What effect does decreasing the frequency have on the sound wave?

Decreases the pitch

500

This is the word we use to measure frequency

What is hertz
