The number of wavelengths that pass a fixed point each second

Question 12

Amplitude

Answer 12

The measure of the size of the disturbance from a wave

Question 13

Refraction

Answer 13

The bending of a wave caused by a change in its speed as it travels from one medium to another

Diffraction

Answer 14

The bending of a wave around an object

Question 15

Interference

Answer 15

The process of two or more waves overlapping, and combining to form a new wave
