Waves

Question 1

Frequency

Answer 1

The number of wave crests passing a fixed point every second

Question 2

Period of a wave

Answer 2

The time taken for a full cycle of the wave, usually measured from peak to peak, or trough to trough

Question 3

Amplitude

Answer 3

The height of a wave crest or trough of a transverse wave from the rest position. For oscillating motion, the amplitude is the maximum distance by an oscillating from it’s equilibrium position

Question 4

Longitudinal wave

Answer 4

Waves in which the vibrations are parallel to the direction of energy transfer

Question 5

Transverse wave

Answer 5

A wave where the vibration is perpendicular to the direction of energy transfer

Question 6

Displacement of a wave

Answer 6

The distance that a certain point in the medium has moved from it’s rest position

Question 7

Wavelength

Answer 7

Distance covered by a full cycle of the wave, usually measured from peak to peak, or trough to trough
