Dispersion 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.

What do water droplets in a rainbow act like?

• prisms
• flashlights
• reflectors
• lasers

What is the spectrum?

• A disturbance that transfers energy from place to place
• The ability to do work
• What we see when specific light reflects off of an object
• The range of visible color

Apart from a prism, light can also be separated by

• rain drop

• air

• plastics

• metal

This is the example of dispersion of light

• sky looks bright orange in the evening

• shadow

• Pool seems shallower

• rainbow

When a ray of light enters a prism,it bends__________the normal.

When a ray of light leaves a prism,it bend________the normal
