A light ray passed through an equilateral prism. If the angles of inci...
Explanation:
Angle of Deviation:
When a light ray passes through a prism, it deviates from its original path due to refraction. The angle of deviation is the angle between the incident ray and the emergent ray after passing through the prism.
Prism Angle:
In an equilateral prism, all angles are 60°. Therefore, the angle of prism = 60°.
Relation between Angle of Incidence, Angle of Emergence, and Angle of Deviation:
The angle of deviation (δ) can be calculated using the formula:
δ = (i + e) - A,
where i = angle of incidence, e = angle of emergence, and A = angle of prism.
Given i = 45° and e = 55°, we can substitute these values into the formula:
δ = (45° + 55°) - 60°
δ = 100° - 60°
δ = 40°
Therefore, the angle of deviation is 40°, which matches option 'D'.
