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