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 = $$\frac{Sin \Theta_r}{Sin \Theta_r}$$
