2
Q
What is amplitude
A
Distance from middle to top (crest) or bottom (trough) of the waves.
3
Q
What is Wave length
A
Distance from one point to another point of the waves
4
Q
Wave length measured in?
A
Metres (m)
5
Q
What is frequency?
A
Number of waves per second
6
Q
Frequency measured in
A
Hertz (Hz)
7
Q

A
Time for one wave to pass
a given point
8
Q
Time period measured in?
A
seconds
9
Q
Equation for Wave Velocity?
A
Wave velocity (M/s) = Frequency (Hz)/(s) * Wave length (m)
10
Q
How to measure velocity of ripples
A
Find Wavelength : Flashing light and a ruler
Find frequency : Number of rotations of the motor per second.
