Question

what do you mean by (a) monochromatic light and (b) polychromatic light? Give examples.

Answer 1

Answer:

monochromatic light has single wavelength and colour.

eg. laser beam

polychromatic light different wavelength and colours.

eg. white light

Answer 2

Monochromatic and polychromatic light

Explanation:

Monochromatic light refers to light that contains only one colour and hence has one particular wavelength associated to the colour of the light. Example: Laser light.

In general, white light is a mixture of seven colours. Each colour has a different wavelength. This spectrum of light is called a polychromatic light. Example: Sunlight.

When white light passes through a prism, it gets refracted into its various components. So you can see all the seven colours on the other side of the prism. White light is made of violet, indigo, blue, green, yellow, orange and red colours.
