Law of Reflection

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 formed between the incident ray and the normal line at the point of reflection.

Front

Define angle of reflection.

Back

The angle of reflection is the angle formed between the reflected ray and the normal line at the point of reflection.

Front

What is a normal line in the context of reflection?

Back

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

Front

If the angle of incidence is 30 degrees, what is the angle of reflection?

Back

30 degrees.

Front

What happens to light when it reflects off a smooth surface?

Back

Light reflects in a uniform direction, resulting in clear images; this is known as specular reflection.

Front

What happens to light when it reflects off a rough surface?

Back

Light scatters in many directions, resulting in a diffuse reflection.

Front

What is specular reflection?

Back

Specular reflection is the reflection of light from a smooth surface, where the angle of incidence equals the angle of reflection.

Front

What is diffuse reflection?

Back

Diffuse reflection occurs when light hits a rough surface and reflects in many directions.

Front

What is the relationship between the incident ray, reflected ray, and normal line?

Back

The incident ray, reflected ray, and normal line all lie in the same plane, and the angle of incidence equals the angle of reflection.
