Question 1

what do waves transfer?

Answer 1

energy

Question 2

what is an electromagnetic wave?

Answer 2

a wave that transfers energy without a need for a substance

Question 3

give an example of an electromagnetic wave

Answer 3

Gamma, X-ray, ultra-violet, light, infra-red, microwave or radio

Question 4

what is a transverse wave?

Answer 4

a wave where the vibration is 90° to the direction in which the energy is transferred

Question 5

what is a longitudinal wave?

Answer 5

a wave where the vibration is parallel to the direction in which the energy is transferred

Question 6
