## Longitudinal Wave

On a longitudinal wave: A compression is a region where particles are close to one another. (High pressure) A rarefaction is a region where the particles are further apart. (Low pressure) For a longitudinal wave at an instant of time, displacement is zero when the particle is at equilibrium position displacement is positive when the particle is displaced to the …

## Parts of A Transverse Wave

Wavefronts show the position of points of a wave which are in phase. Displacement is the distance moved by the particle from its equilibrium position. The amplitude of a wave is the maximum displacement of the particle from its equilibrium position. The wavelength is the distance between 2 successive points on a wave which are in phase with one …

## Types of Waves

Waves provide a mechanism for the transfer of energy from one point to another, there is no transfer of any material between the points. Waves can be classified as: Mechanical OR Electromagnetic Transverse OR Longitudinal Progressive(travelling) OR Stationary (standing) Mechanical Require a medium for propagation Particles of medium oscillate but do not propagate Electromagnetic Require no medium for propagation(can travel …

## Standing Waves on a string

Standing waves on a string are produced only at specific frequencies. For string fixed at both ends: For string fixed at one end: At closed/fixed ends, there must be nodes. At open/loose ends, there must be antinodes. End correction, e (for air column):

## Stationary Waves

Stationary waves occur when two waves that meet are: of the same type of the same frequency of the same amplitude travelling in opposite directions If two waves with amplitude A meets,   Properties of stationary waves: Every point bounded within two consecutive nodes is in phase with one another. (reach amplitude/equilibrium positions at the same time) Points bounded within …

## Diffraction Grating

Diffraction grating is an array of a large number of parallel, evenly spaced slits of the same width. When light is shone through a diffraction grating, bright and sharp fringes can be observed at several angular position with the aid of a spectrometer $d \, sin \, \theta = m \lambda$, where d is slit separation, m is the order …
