Physics P14 - Light

Front

What is a 'Virtual image'?

Back

An image formed at a place where the light rays appear to come from after they've been reflected (or refracted).

Front

The image formed by a plane mirror is:

Back

Virtual and upright.

Front

When light enters a more dense medium, the refracted wave slows down and bends towards the normal. True or False?

Back

True.

Front

What is a 'Plane mirror'?

Back

A mirror with a flat (planar) reflective surface.

Front

What is 'Magnification'?

Back

The image height ÷ the object height.

Front

What is 'Reflection of Light'?

Back

The bouncing back of light rays when they hit a surface.

Front

What is 'Refraction of Light'?

Back

The bending of light rays as they pass from one medium to another.

Front

What is the 'Normal Line' in optics?

Back

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

Front

What does 'Concave mirror' do to light rays?

Back

It converges light rays to a focal point.

Front

What does 'Convex mirror' do to light rays?

Back

It diverges light rays, making them appear to come from a focal point behind the mirror.
