Given:
A ray of light incident on a refracting surface. If the angle of incidence 60° and the angle of refraction is 45°.
To find:
Angle of Deviation
Calculation:
Let light be incident at the interface of 2 media. The angle of incidence be i and angle of refraction be r.
Let deviation be
Since light is going from rarer to denser medium , hence :
Deviation is 15° in CLOCKWISE direction.
