WAVES, SOUND AND LIGHTUNIT 1 – TRANSVERSE PULSES
Pulse A single disturbance in a medium
Transverse pulse A pulse in which the particles of the medium move at
right angles to the direction of motion of the pulse
Amplitude The maximum disturbance of a particle from its rest
(equilibrium) position
The principle of superposition Is the algebraic sum of the amplitudes of 2 pulses that
occupy the same space at the same time
Constructive interference Is the phenomenon where the crest of one pulse
overlaps with the crest of another to produce a pulse of
increased amplitude
Destructive interference Is the phenomenon where the crest of one pulse
overlaps with the trough of another, resulting in a pulse
of reduced amplitude
Transverse wave A wave in which the particles of the medium vibrate at
right angles to the direction of motion of the wave
Wavelength The distance between two successive points in phase
Frequency The number of wave pulses per second
Period The time taken for one complete wave pulse
Crest Is highest point (peak) on a wave
Trough Is lowest point on a wave
Wave speed The distance travelled by a point on a wave per unit
time
Longitudinal wave A wave in which the particles of the medium vibrate
parallel to the direction of motion of the wave
Compression A region of high pressure in a longitudinal wave
Rarefaction A region of low pressure in a longitudinal wave
