Properties of Waves
How high a wave moves from the equilibrium line
What is amplitude?
What is a medium?
A substance that can carry a wave (solid, liquid, gas)
Calculate the speed of a wave with a wavelength of 5m and a frequency of 6Hz
30m/s
The high point of a wave
What is crest?
Waves that do not need a medium
What are electromagnetic waves?
What do waves carry?
What is energy?
True or false: sound waves need a medium
True
Calculate the speed of a wave with a wavelength of 4m and a frequency of 12Hz
48m/s
The low point of a wave
Waves that need a medium
The distance between two troughs of a wave
What is wavelength?
Can waves travel in space?
Sound waves cannot, but light waves can!
Calculate the wavelength of a wave with a speed of 18m/s and a frequency of 9Hz
2m
The number of waves that pass through a point in a second
Sound waves are which type of wave?
What happens in constructive wave interference?
Two waves come together and make a bigger wave
Sound travels fastest through which state of matter?
Solid
Calculate the frequency of a wave with a speed of 64m/s and a wavelength of 4m
16Hz
The distance from one crest to the next
What is wavelength?
Light waves are which type of wave?
Transverse or electromagnetic
If frequency increases, what will happen to the pitch of a sound?
It will increase
Why does sound travel faster through a solid?
Because the particles are more compact (dense) in a solid than in a liquid and a gas
Calculate the wavelength of a wave with a speed of 108m/s and a frequency of 12Hz
9m
Another word for wave speed
What is velocity?
The combination of transverse and longitudinal waves
What is surface waves?
