Dispersion

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

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

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.

What is being blocked when a shadow is formed?

• Light Source
• Light Path
• Object
• Eye

Which images are opaque?

• A & C
• A,C,E, & F
• D, E, & F
• A & E

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

• Because light reflects off the prism's surface

• The incident white light refracts and separates into its constituent colors

• The white light is absorbed by the prism, separating its colors

• The light speeds up as it moves from air into the denser plastic material
