Dispersion

How many components of white light?

• 5

• 6

• 7

• 8

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

Why is the spectrum of light seperated into its components of colour when white light is directed to a prism?

• The different colours in the white light bend away from the normal line at different angles when entering prism

• The different colours in the white light bend towards the normal line at different angles when entering prism

• The different colours in the white light bend away from the normal at same speed to each other when entering prism

• The different colours in the white light bend towards the normal at same speed to each other when entering prism

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

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

Which color refracts the least from the 7 colors of the rainbow?

Which of the following colours gets bent the least after refraction?

• Green

• Yellow

• Violet

• Blue

Which of the following colours gets bent the most after refraction?

• Yellow
