# Finding Wavelength from Diagram

### Finding wavelength from diagram

#### Transverse Wave

Wavelength is the distance between two successive crest or trough.

#### Longitudinal Wave

Wavelength is the distance between two successive compression or rarefaction.

#### Wave front diagram

Wavelength is the distance between two successive wave front

Example 1:

Figure above shows the propagation of a water wave. What is the amplitude of the wave?

$Amplitude= 10cm 2 =5cm$

Example 2 :

The figure above shows a transverse wave. The wavelength of the wave is equal to
$Amplitude= 2 3 ×x= 2 3 x$
$3λ=15cm λ= 15 3 =5cm$
$2λ=25cm λ= 25 2 =12.5cm$
