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

Types of waves
