The angle between the refracted ray and the normal is called the angle of incidence.
The angle between the incident ray and the refracted ray is called the angle of deviation.
What is an angle made between the incident ray and normal at the point of incidence called?
Draw a ray diagram showing the passage of light through a glass slab and label the following:
incident ray, normal, angle of incidence, refracted ray, angle of refraction, emergent ray, angle of emergence
