Dispersion of Light

How many colours make up white light?

• 5

• 6

• 7

• 8

These are all colours of the spectrum except for

• indigo

• blue

• purple

• green

An example of dispersion of light

• sky looks bright orange in the evening

• shadow

• Pool seems shallower

• rainbow

Why can we see a spectrum of colours when white light passes through a glass prism?

• phenomenon of scattering of light

• phenomenon of dispersion of light

• phenomenon of reflection of light

• phenomenon of diffraction of light

Explain how white light is separated into its component colours when white light is passed through 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

Why is red light is at the top and violet light 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.
