Refraction and Reflection of Light

Front

What is an electromagnetic wave?

Back

An electromagnetic wave is a transverse wave that consists of oscillating electric and magnetic fields, propagating through space.

Front

What type of image is formed by the actual intersection of light rays?

Back

A real image is formed by the actual intersection of light rays and can be projected onto a screen.

Front

What is amplitude in the context of waves?

Back

Amplitude is the maximum displacement of a particle from its rest position in a wave.

Front

What is the focal length of a spherical mirror?

Back

The focal length is the distance between the pole of the mirror and its principal focus.

Front

Which electromagnetic wave has the longest wavelength?

Back

Radio waves have the longest wavelength among electromagnetic waves.

Front

What is reflection of light?

Back

Reflection of light is the bouncing back of light rays when they hit a surface.

Front

What is refraction of light?

Back

Refraction is the bending of light rays as they pass from one medium to another due to a change in speed.

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 a virtual image?

Back

A virtual image is formed by the apparent intersection of light rays and cannot be projected onto a screen.

Front

What is the difference between concave and convex mirrors?

Back

Concave mirrors converge light rays to a focal point, while convex mirrors diverge light rays.
