# Physics Course/Waves/Wave Refraction

## Wave Refraction

Wave refraction is a phenomenon observed when wave travels and hits a blocking object at a deflected angle instead of passing through the object in straight line.

## Angle of Refraction

If θi represents the incident angle and if wave travels in straight line then the angle of refraction is equal to angle of incident

θr = θi

If wave travels is being deflected at angle θr Then the deflection can be calculated by

Degree of Refraction = ${\displaystyle {\frac {Sin\Theta _{r}}{Sin\Theta _{r}}}}$
