One of the refracting surfaces of a prism of refractive index √2...
Given Information:
- Refractive index of prism = √2
- Critical angle of medium = Angle of prism
- Ray retraces its path after reflection at the silvered face

Solution:

1. Critical Angle:
- Critical angle of medium = Angle of prism
- sin(critical angle) = 1/√2 (as refractive index = √2)
- Critical angle = 45 degrees

2. Ray Retraces its Path:
- When a ray retraces its path after reflection, angle of incidence = angle of reflection
- Angle of incidence on unsilvered surface = angle of reflection on silvered surface
- Let this angle be x

3. Using Laws of Reflection:
- Angle of reflection = Angle of incidence = x
- Since the angle of prism is equal to the critical angle of the medium (45 degrees), the angle of incidence on the unsilvered surface is also 45 degrees.
Therefore, the correct answer is option C) 45 degrees.
