Solution
The correct option is D angle of incidence = angle of emergence
When a ray of light is incident on an equilateral glass prism placed in minimum deviation position the angle of incidence and angle of emergence are equal. The ray diagram is shown below.\
In this position, both the angle of incidence and the angle of emergence are equal, i.e.,
Angle of incidence (i) = Angle of emergence (e)
angle of incidence = angle of emergence
When a ray of light is incident on an equilateral glass prism placed in minimum deviation position the angle of incidence and angle of emergence are equal. The ray diagram is shown below.\
In this position, both the angle of incidence and the angle of emergence are equal, i.e.,
Angle of incidence (i) = Angle of emergence (e)
