waves

what is a period

time in which a particle of the medium completes one oscillation

what is frquency

number of complete waves passing a point per second

what is wavelength

distance travellled by the wave in the time in which a particle medium completes one oscillation

what is velocity

distance travelled by the wave in one second

what is displacement

distance moved by the wave in one second

what is amplitude

maximum displacement of a particle of the medium from its mean position

what is a phase

position of a particle of the medium within the cycle of oscillation

unit for period

seconds

unit for frequency

hertz

unit for wavelength

metres

unit for velocity

metres per second

units for displacement

metres

units for amplitude

metres

units for phase

angles in radians

what is the phase difference between particles which are a wavelength apart

2 (pi)

what is a progressive wave

wave in which energy is trasnferred from one place to another as a result of its motion

how is energy transferred by a wave

through ossilation

what is a mechanical wave

vibrations of particles of a medium

what type of waves don’t need particles to move

electromagnetic waves
