Question 1

define frequency

Answer 1

NUMBER of waves passing a stationary point each second

Question 2

define period

Answer 2

TIME taken for 1 wave to pass a stationary point

Question 3

define amplitude

Answer 3

maximum displacement from an equilibrium position

Question 4

define wavelength

Answer 4

distance between a point on a wave and the next identical point on a wave

Question 5

define wavefonts

Answer 5

represents peak of each wave

Question 6

define coherence

Answer 6

waves which have the same frequency, wavelength and have constant phase difference

Question 7

define oscillation

Answer 7

a regular repetitive motion back and forth through a point

Question 8

define transverse

Answer 8

particles on a wave oscillate perpendicular to direction of wave travel

Question 9

define longitudinal

Answer 9

particles on a wave oscillate parallel to direction of wave travel

Question 10

define phase difference

Answer 10

the amount by which one wave leads or lags (falls behind) another wave

OR

distance between two points on the same wave

Question 11

define path difference

Answer 11

the difference in length between two rays

Question 12

define stationary wave

Answer 12

energy is stored rather than transferred to other locations

Question 13

define displacement

Answer 13

distance moved by a wave or particle or medium from it’s original position

Question 14

define progressive wave

Answer 14

wave fonts move away from the source transferring the energy from one place to another
