a beam of light is too be deviated through 60 degree by use of plane mirror. what must be the angle between the mirror and the direction of incident light?
Answers
Explanation:
As shown in the figure ,when the incident ray deviates by 60° after refraction means reflected angle makes an angle 30° with the mirror and the other 30°is made with the undeviated light behind the mirror.
As seen from the figure ,but symmetry and due to law of refraction ( angle of incidence is equals to angle of reflection).incident angle makes an angle 30° with the mirror.
angle of incidence=angle of reflection =60°.
