1
Q
Amplitude:
A
The amplitude of a wave is the maximum distance that the wave moves from its restitution.
2
Q
Frequency:
A
The number of wavelengths that pass by a point each second.
3
Q
Calculating a wave’s frequency:
A
Divide the number of wavelengths by the time. (use Hz)
As the frequency of a wave increases, the wavelength decreases.
4
Q
Calculating a wave’s speed:
A
multiply the wavelength by the frequency
