Separation of Light

When light travels through a prism it spits the white light into _______ colours

• 5

• 3

• 7

• 9

The separation of visible light into is different colours is known as __________________

• displays

• dispersion

• reflection

• refraction

The separation of colours by a glass prism produces a

• selection

• arrangement

• colour belt

• spectrum

When light touches the surface of a prism refraction takes place, in simple terms the light

• bends

• gets longer

• straightens

• curls up

For separation of light into its component colours, the light needs to hit the prism

• through the air

• through the water

• straight on

• at an angle

Apart from a prism, light can also be separated by

• rain drop

• air

• plastics

• metal

Light can be dispersed artificially by

• rain drop

• air

• a prism glass

• clear plastic

Natural dispersion is when _________ passes through rain drops to give rainbow.

• sunlight

• air

• dust

• snow

One of these colours go at the bottom of a light separation diagram because it has the shortest wave length

• Red

• Orange

• Violet

• Green

One of these colours go at the top of a light separation diagram because it has the longest wave length

• Red

• Orange

• Violet

• Green
