Sirs Mini Test - Wave Definitions

Question 1

Define a transverse wave

Answer 1

A type of wave in which the particles oscillate at right angles to the direction the wave travels

Question 2

Give me an example of a transverse wave

Answer 2

UNACCEPTTABBBBBLEEEEEEE CONDITIOOOOON

JK - eg. Electromagnetic waves, water and s-waves

Question 3

Define a longitudinal wave

Answer 3

A type of wave in which the particles oscillate parallel to the wave direction,

Question 4

OI OI give me an example of a longitudinal wave

Answer 4

Eg. Sound waves, seismic p waves

Question 5

Define wavelength

Answer 5

It’s the distance between 2 matching points on neighbouring waves, measured in metres

Eg peak to peak or trough to trough

Question 6

Define the amplitude

Answer 6

The amplitude or any wave is the max displacement a Point on the wave moves from the centre of the oscillation, (/rest position) in metres

Larger amplitude, greater the energy of the wave

Question 7

Define the period of a wave

Answer 7

Time period, T is the time taken for a point on a wave to move through one complete oscillation in seconds

Question 8

Define the frequency

Answer 8

Frequency, f of any wave is the number of oscillations per second measured in hertz, Hz

Frequency = 1/ T
