15.3 - Transverse & longitudinal waves, & parts of a wave (learn diagram!!)

transverse wave

wave where the direction of vibration is perpendicular to the direction in which the wave travels

longitudinal wave

wave where the direction of vibration is parallel to the direction in which the wave travels

top of a wave

crest

bottom of a wave

trough

wavelength

distance from any point on one cycle to the corresponding point on the next cycle

wavelength is measured in

metres

frequenecy

number of wave cycles passing any point per second

1 hertz (Hz)

1 cycle per second is called 1Hz

all..

electromagnetic waves are transverse waves

E.g of transverse waves (2)

Waves on a rope/spring, water waves

E.g of longitudinal waves

Sound waves in a solid.

Cycle

Aka oscillation, is the disturbance produced by 1 complete vibration of the source- 1 crest and 1 trough
