3.2-3.9 properties of waves

Question 1

whats the difference between longditudinal and transverse waves

Answer 1

perpendicular:
direction of the wave is perpendicular to the oscillation

parallel:
direction of the wave is parallel to the oscillation

Question 2

how do you calculate wave speed?

Answer 2

wave speed= frequency x wavelength

Question 3

how do you calculate frequency?

Answer 3

frequency= 1/time period

Question 4

describe the doppler effect

Answer 4

in the way an object is moving the wavefronts bunch up and behind they spread out

if an object is moving towards a stationary observer these bunched up waves are percieved at a higher frequency and opposite

Question 5

define the doppler effect

Answer 5

the apparent change in the frequency of a wave caused by relative motion between the source of the wave and the observer

Question 6

define refraction

Answer 6

when light passes a boundary between two different transparent media

Question 7

define reflection

Answer 7

when a wave hits boundary between two media where the wave speeds differ, but the wave stays in the original medium instead of passing into the second medium
