## Definition

Wave represents a periodic motion that carries energy travels in space . Example, Light wave, Sound wave , Radiation wave , Electric wave , Electromagnetic wave ...

## Fundamental waves

### Transverse wave Transverse wave represents a wave that travels horizontally . For example Electric oscillation wave , Spring oscillation wave . Transverse wave has the following characteristics

• Wave function
$x(t)=A\sin \omega t$ • Wave equation
$x^{''}(t)=-\omega x(t)$ • Angular frequency
$\omega =\lambda f$ ### Logitudinal wave

Longitudinal wave represents a wave that travels vertically . For example Light oscillation wave , Sound oscillation wave . Transverse wave has the following characteristics

• Wave function
$y(t)=A\sin \omega t$ • Wave equation
$y^{''}(t)=-\omega y(t)$ • Angular frequency
$\omega =\lambda f$ ### Tranlate wave Transverse wave represents a wave that travels at an inclined angle . For example Electromagnetic oscillation wave . Transverse wave has the following characteristics

• Wave function
$x(t)=A\sin \omega t$ $y(t)=A\sin \omega t$ • Wave equation
$x^{''}(t)=-\omega x(t)$ $y^{''}(t)=-\omega y(t)$ • Angular frequency
$\omega =\lambda f$
