Physics [waves] Flashcards
Definition of a wave
A wave is a disturbance that transfers energy from one place to another, it does not transfer matter
Definition of periodic motion
Periodic motion is a motion repeated at regular intervals
What is a wave made up of
Periodic motion
Definition of a transverse wave
Transverse waves are waves in which the particles vibrate perpendicular to the wave direction
Definition of longitudinal waves
Longitudinal waves are waves in which the particle vibrate parallel to the wave direction.
Examples of a transverse wave
Water and light
Examples of longitudinal waves
Sound
Trough definition
Lowest point of a transverse wave
Crest definition
Highest point of a transverse wave
Definition of a wavelength
The shortest distance between any two points in phase
The amplitude of a wave is
The maximum displacement of a point from its rest position
Sl unit of wavelength and amplitude
. Metre (m)
Frequency formula
F= 1/t
Velocity formula
V= fλ
