Dispersion of Light

The breaking up of white light into its component .

Based on the statement given, name the process that takes place in the white light.

• Dispersion

• Reflection

• Refraction

• Scattering

Why is the component of colour in a rainbow can be seen when light passes through a glass prism?

• phenomena of scattering of light

• phenomena of dispersion of light

• phenomena of reflection of light

• phenomena of diffraction of light

How many components of white light?

• 5

• 6

• 7

• 8

This is the example of dispersion of light

• sky looks bright orange in the evening

• shadow

• Pool seems shallower

• rainbow

These are all colours of spectrum except

• indigo

• blue

• purple

• green

Why is red light is at the top whileviolet at the bottom of the spectrum?

• Violet light has the medium speed so it is refracted the least.

• Violet light has the highest speed so it is refracted the least

• Red light has the slowest speed so it is refracted the least

• Red light has the highest speed so it is refracted the least.

Rainbow is formed due to

• Natural dispersion

• Sunlight passing through raindrops

• Refraction of light

• All of the above

A transparent object that bends light into rainbow colors.

• prism

• mirror

• convex lens

• concave lens

The dispersion of light is the separation of white light into the spectrum of light, namely red, orange, yellow, green,blue,indigo and violet.

• True

• False

Violet light is refracted the most by a glass prism as the light travels the ................ through the glass prism.

• slowest

• fastest
