Answer: The angle between the incident ray and the normal ray is called as the angle of incidence.
Explanation:
For the given options:
- Option A: The angle of refraction
Angle of refraction is defined as the angle formed between the refracted ray and the normal ray drawn at the point of interference.
- Option B: The angle of reflection
Angle of reflection is defined as the angle formed between the reflected ray and the normal ray.
- Option C: The angle of incidence
Angle of incidence is defined as the angle formed between the incident ray and the normal ray.
Hence, the angle between the incident ray and the normal ray is called as the angle of incidence.
