प्रश्न
The angle between incident ray and reflected ray is 60°. What is the value of angle of incidence? Given that, angle of incidence + angle of reflection = 60°.
उत्तर
The angle made between the reflected ray and incident ray includes the angle of incidence and angle of reflection. So, we have, i + r = 60°
Also, we know that angle of incidence is equal to angle of reflection.
So, we have, i = r
Therefore, i + i = 60°
i = `(60°)/2` = 30°
