Longitudinal and Transverse waves

Question 1

Distance

Answer 1

How far the wave has travelled from its starting point.

Question 2

Displacement

Answer 2

How far from the equilibrium point the wave has oscillated. (How far it’s gone up or down)

Question 3

Amplitude

Answer 3

The maximum displacement.

Question 4

Wave length

Answer 4

Distance of one entire oscillation. (The top of one wave to the top of the next)

Question 5

Time period

Answer 5

The time it takes to complete one full oscillation

Question 6

Equation for Frequency

Answer 6

F = 1 / time (Measured in hertz)

Question 7

Frequency

Answer 7

The number of complete oscillations per second.

Question 8

Equation of Time

Answer 8

time = 1/f

Question 9

Equation of wave speed

Answer 9

Wave speed (V) = f x wave leangth (lambda)

Question 10

Transverse waves

Answer 10

The oscillations are perpendicular to the direction of energy transfer. e.g. light, radio, string, water

Question 11

Longitudinal waves

Answer 11

Oscillations are parallel to the direction of energy transfer. (Some areas are spread out and some areas are more compressed) e.g. Sound waves
