Transverse and longitudinal waves

Question 1

What occurs when a wave travels through a medium

Answer 1

particles of the medium oscillate and transfer energy between each other - particles stay in same place, only energy is transferred

Question 2

Top of wave =
Bottom of wave =

Answer 2

crest
trough

Question 3

What’s a frequency ?

Answer 3

Number of complete waves passing a certain point per sec.
1 Hz = one wave per second

Question 4

What’s a amplitude ?

Answer 4

maximum displacement of a point on the wave from its equilibrium position

Question 5

What’s a wavelength ?

Answer 5

Distance between same point on two adjacent waves

Question 6

Formula that links wave speed ,frequency and wave length

Answer 6

v = f(\lambda )

wave speed ( m/s) = frequency ( Hz ) x wavelength ( m )

Question 7

What is a transverse wave ?

Answer 7

Oscillation are perpendicular ( up and down ) to the direction of energy transfer
types include :
- electromagnetic waves
- waves on a string
- seismic s waves
- water waves

Question 8

What is a longitudinal wave ?

Answer 8

Oscillation are parallel ( side ) to the direction of energy transfer .
types include :
- sound waves
- seismic p waves
