Wave Properties

Question 1

define a longitudinal wave

Answer 1

particles (or wave) vibrate in same direction as energy transfer

Question 2

define a transverse wave

Answer 2

particles (or wave) vibrate perpendicular to direction of energy transfer

Question 3

example of longitudinal wave

Answer 3

sound

Question 4

example of transverse wave

Answer 4

light

Question 5

define wavelength

Answer 5

distance between successive crests

Question 6

define amplitude

Answer 6

half the vertical distance between crest and trough

Question 7

define period

Answer 7

time for one wave to pass a point

Question 16

define crest

Answer 16

highest point of a wave

Question 17

define trough

Answer 17

lowest point of a wave

Question 18

what do all waves transfer?

Answer 18

energy

Question 19

as wavelength increases, what happens to frequency if the speed remains the same?

Answer 19

decreases
