100

A repeating disturbance that travels from one location to another, transferring energy through matter or space, is called what?

A wave

100

What type of wave has the largest/longest λ?

Radio waves

100

What does this symbol stand for?

λ

Wavelength

100

This part of a transverse wave is the highest point, where the wave reaches its maximum displacement from the rest position.

Crest

100

What is the area of the wave where particles are spread apart?

Rarefaction

200

What are the two types of waves?

Transverse and longitudinal.

200

What type of wave has the smallest/shortest λ?

Gamma rays

200

What is the wave speed formula?

V = f x λ

200

This is the distance from the equilibrium to the crest or trough of a wave.

Amplitude

200

True or false, all longitudinal waves are mechanical.

True, all longitudinal waves require a medium to transfer energy.

300

The time it takes for one λ to pass is known as this.

Period

300

True or false, EM waves require a medium to travel through.

False only mechanical waves require a medium.

300

What unit of measure is used for frequency?

Hz
Hertz

300

This term describes the distance from one crest to the next or from one trough to the next.

λ

300

λ is measured from what to what?

Compression to compression

400
The number of wavelengths that pass in one second is called the wave's what?

Frequency

400

True or false microwaves have more energy than x-rays?

False
Microwaves have less energy, longer wavelengths and lower freq than X-rays.
Microwaves follow radio waves on the EM spectrum.

400

If a wave travels with a frequency of 3Hz and a λ of 6m, what is its speed?

18 m/s

400

This is the midpoint or resting place of the oscillating particles of a wave.

Equilibrium

400

Mechanical waves need what in order to transfer energy?

a medium

500

This is when a wave changes direction due to the change in speed as it travels from one medium to another.

Refraction

500

What is the speed at which all EM waves travel?

3x108
300,000,000
Light Speed

500

What is the λ of a wave with a speed of 24m/s and a frequency of 16Hz?

1.5m

500

How does the medium oscillate in relation to the direction of energy movement?

perpedicular
900

500

How does the medium oscillate in relation to the direction of energy movement

Along the direction of travel
