Reflection FLASHCARD

Front

What is a virtual image?

Back

A virtual image is an image that cannot be projected onto a screen; it appears to be located behind the mirror or lens.

Front

What does the angle of reflection refer to?

Back

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

Front

If a ray of light is incident on the normal, what is the angle of reflection?

Back

0 degrees.

Front

What is the normal line in reflection?

Back

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

Front

What is specular reflection?

Back

Specular reflection is the reflection of light from a smooth surface, resulting in a clear image.

Front

What is diffuse reflection?

Back

Diffuse reflection occurs when light hits a rough surface and scatters in many directions, producing a blurry image.

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

What is an incident ray?

Back

An incident ray is the incoming ray of light that strikes a surface.

Front

What is a reflected ray?

Back

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

Front

What is the difference between a real image and a virtual image?

Back

A real image can be projected onto a screen and is formed by converging light rays, while a virtual image cannot be projected and is formed by diverging light rays.
