Answer 7

distance from point of wave to equivalent point of adjacent wave

Question 8

Amplitude

Answer 8

Maximum displacement of point on wave from undisturbed position

Question 9

Frequency

Answer 9

number of waves passing a fixed point per second

Question 10

Period

Answer 10

time taken for each wave pass a fixed point

Question 11

Frequency/period equation

Answer 11
