Question

If the angle between normal and incident ray is 30 then what is the angle between incident and reflected ray

Answer 1

Explanation:

The angle formed by the incident and reflected rays is the sum of the angle of incidence and angle of reflection, and is therefore 30 degrees + 30 degrees = 60 degrees.

Answer 2

The angle between incident and reflected ray is 60°

Explanation:

• Given data

• Angle of incident = angle between normal and incident ray = 30°

• From First law of reflection

       Angle of reflection = Angle of incident

• Means

       Angle of reflection =  30°

       Angle of reflection =30°=the angle between normal and reflected ray

• Angle between incident and reflected ray=Angle of incident+Angle of reflection

      Angle between incident and reflected ray = 30°+30° =60°
