Question

angle between the incident ray and mirror is Ө. The total angle formed by the ray of light is 80° . The value of Ө is

Answer 1

• value of theta 50. angle b/w incident ray and reflect ray is 80. according to mirror law, angle of incidenc and angle of reflect is equal and these angle made in plane so,I take theta as x then 2x+80=180,. x =50.

Answer 2

Explanation:

angle b/w incident ray and reflect ray is 80. according to mirror law, angle of incidenc and angle of reflect is equal and these angle made in plane so,I take theta as x then 2x+80=180,. x =50
