Laws of reflection

Front

What is the light-sensing organ in humans?

Back

The eye.

Front

What is the angle called when light bounces off a reflecting surface?

Back

Angle of reflection.

Front

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

Back

30 degrees.

Front

In a reflection diagram, what does the angle of incidence represent?

Back

The angle between the incoming light ray and the normal line.

Front

Why can we see most objects?

Back

Because light reflects off them.

Front

What is the law of reflection?

Back

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

Front

What is the normal line in the context of reflection?

Back

An imaginary line perpendicular to the reflecting surface at the point of incidence.

Front

What happens to light when it hits a rough surface?

Back

It scatters in many directions.

Front

What is the difference between specular and diffuse reflection?

Back

Specular reflection occurs on smooth surfaces, while diffuse reflection occurs on rough surfaces.

Front

How does the angle of incidence affect the angle of reflection?

Back

They are always equal according to the law of reflection.
