Reflection FLASHCARD

Front

What is a Virtual Image?

Back

An image that can be seen but does not actually exist; it appears to be located behind the mirror or lens.

Front

What must the zero degree line on a protractor line up with when measuring angles?

Back

The normal.

Front

What is Specular Reflection?

Back

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

Front

What is the angle of incidence?

Back

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

Front

What is the angle of reflection?

Back

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

Front

What is the Law of Reflection?

Back

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

Front

What is a Real Image?

Back

An image that can be projected onto a screen; it is formed when light rays converge.

Front

What is the difference between a Real Image and a Virtual Image?

Back

A real image can be projected onto a screen, while a virtual image cannot; virtual images appear to be behind the mirror.

Front

What is the purpose of a protractor?

Back

A tool used to measure angles in degrees.

Front

What is the normal line in optics?

Back

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