DISPERSION AND SCATTERING OF LIGHT

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

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

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.

Look at the diagram given. This is the first prism. What happen if A SECOND inverted prism is placed behind the first prism?

• the various colours pass through it and form brighter spectrum

• the various colours pass through it and form a white light back

• the various colours pass through it and form an opposite spectrum colours

• nothing will happen

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

these are examples of phenomenon of scattering of light except

• Sky appears blue at midday

• Sky appears reddish in the evening

• Rainbow after rain

Why does scattering of light occur?

• Light rays are blocked and reflected to all directions by the clouds or particles in the air

• Light rays are blocked and reflracted to all directions by the clouds or particles in the air

• Light rays are passing through and refracted to all directions by the clouds or particles in the air

This is a phenomena scattering of wave during ______________ .

Blue colour is scattered _______ compared to the ______ colour.

• sunset, more, yellow

• sunset, less, red

• the day, more, yellow

• the day, less, yellow
