Question

The incorrect statement about the angle of incidence for a wave is:

• A. It can be measured between the incident ray and the normal
• B. It is equal to the angle of refraction
• C. It is equal to the angle of reflection
• D. A normal is the line perpendicular to the surface at the point of incidence

Answer 1

The correct option is B It is equal to the angle of refraction

Angle of incidence is the angle between incident ray and the normal. Normal is the line we draw perpendicular to the surface, at the point of incidence. Angle of incidence is equal to angle of reflection but it is not always equal to the angle of refraction.
