0
Q
What is the amplitude?
A
The length from the rest position to the crest.
1
Q
What is a wavelength?
A
The length from the crest of one wave to another.
2
Q
What unit is frequency measured in?
A
Hertz (Hz)
3
Q
What are transverse waves?
A
Waves where the vibrations are perpendicular to the direction of energy transfer of the wave.
4
Q
What are longitudinal waves?
A
Waves where the vibrations are parallel to the direction of energy transfer of the wave.
5
Q
What units are used to measure to speed, frequency and wavelength?
A
Speed = Metres per second (m/s) Frequency = Hertz (Hz) Wavelength = Metres (m)
6
Q
Can waves be reflected, refracted and diffracted?
A
Yes.
7
Q
What is the law of reflection?
A
Angle of incidence = angle of reflection
