If the angle of reflection of a propagated ray is 35°. Calculate the a. Angle of incidence b. Angle of deviation c. Angle of glance

First of all,

We have,

➝ Angle of reflection = 35°

(a) According to law of reflection,

Angle of incidence = Angle of reflection

➝ Angle of incidence = 35°

(b) By using formula,

Angle of Deviation = 180° - 2(Angle of incidence)

From (a),

➝ Angle of Deviation = 180° - 2(35°)

➝ Angle of Deviation = 180° - 70°

➝ Angle of Deviation = 110°

(c) We know,

Angle of Incidence + Glance angle of incidence = 90°

Angle of reflection + Glance angle of reflection = 90°

So,

As angle of incidence = angle of reflection

Then, Angle of glance is also equal.

➝ Angle of glance = 90° - 35° = 55°
