Practice Question
1.What do waves transfer?
Waves transfer energy and information, but not matter
2.State the names of the two types of waves
Transverse
Longitudinal
2a. Write a definition for a transverse wave
Transverse wave vibrates at 90 degrees to the direction in which it transfers energy
3. Give two examples of a transverse wave
