3
Q
What is frequency
A
The number of waves passing a point each second - measured in hertz (Hz)
4
Q
Give an example of two types of longitudinal waves
A
Sound waves and seismic p waves
5
Q
Give three examples of transverse waves
A
Water surface waves, electromagnetic waves, seismic S waves
6
Q
In a longitudinal wave, what direction do the particles move in
A
Move back and fourth along the same direction as the wave
7
Q
What direction do particles move in a transverse wave
A
At right angles across the direction of the wave
8
Q
What is one wave per second in hertz
A
1Hz
9
Q
What is the equation for wave speed
A
Wave speed = frequency x wavelength
OR
wave speed = distance / time
