Light Waves

Front

What is the angle of incidence?

Back

The angle formed between the incident ray and the normal line at the point of incidence.

Front

What is the angle of reflection?

Back

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

Front

What is reflection in terms of light waves?

Back

The bouncing of light waves off a surface.

Front

What is refraction?

Back

The bending of light as it changes mediums.

Front

What is diffraction?

Back

The bending of light around an object.

Front

What is absorption in the context of light?

Back

Energy of light is absorbed by an object, which can be selective.

Front

How does the angle of incidence relate to the angle of reflection?

Back

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

Front

What is the normal line in optics?

Back

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

Front

What happens to light when it passes from air into water?

Back

It bends towards the normal line due to refraction.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing of light, while refraction is the bending of light as it passes through different mediums.
