Lable the wave diagram with the following:
•amplitude
•peak
•trough
•resting point
•wavelength
Q1. Waves may be longitudinal or transverse. Describe the differences between longitudinal waves and transverse waves.
[3 marks]
The frequency tells us the distance between one point on a wave and the same point on the next wave
The amplitude tells us the displacement of the wave from its resting position
The period is the time taken to complete one wavelength
Waves transfer matter and energy.
Light waves are transverse waves.
