Reflection of Waves

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

Define angle of incidence.

Back

The angle of incidence is the angle between the incident ray and the normal to the surface at the point of incidence.

Front

Define angle of reflection.

Back

The angle of reflection is the angle between the reflected ray and the normal to the surface at the point of reflection.

Front

What is a normal line in wave reflection?

Back

A normal line is an imaginary line that is perpendicular to the surface at the point of incidence.

Front

What happens to the wavelength of a wave upon reflection?

Back

The wavelength of a wave does not change upon reflection.

Front

What is the relationship between the angle of incidence and the angle of reflection?

Back

The angle of incidence is always equal to the angle of reflection.

Front

What is the definition of a reflected ray?

Back

A reflected ray is the ray that bounces off the surface after striking it.

Front

What is the definition of an incident ray?

Back

An incident ray is the ray that strikes the surface before being reflected.

Front

What is the focal point in wave reflection?

Back

The focal point is the point where rays of light or waves converge after reflection.

Front

What is the significance of the normal line in wave reflection?

Back

The normal line is crucial for measuring angles of incidence and reflection.
