The breaking up of white light into its component .
Based on the statement given, name the process that takes place in the white light.
Dispersion
Reflection
Refraction
Scattering
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
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.
Rainbow is formed due to
Natural dispersion
Sunlight passing through raindrops
Refraction of light
All of the above
A transparent object that bends light into rainbow colors.
prism
mirror
convex lens
concave lens
The dispersion of light is the separation of white light into the spectrum of light, namely red, orange, yellow, green,blue,indigo and violet.
True
False
Violet light is refracted the most by a glass prism as the light travels the ................ through the glass prism.
slowest
fastest
Red light is refracted the least by a glass prism because red light travels the ............ through the glass prism
slowest
fastest

Air particle
Dust
Raindrop
soot
Which of the following is NOT a source of light?

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

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
Why does the Sun appear red at sunset?
Red light is the least scattered and travel the longer distance.
Red light is the most scattered and travel the shorter distance.
Red light is the least scattered and more blue light are scattered.
All the components of white light are absorbed by the atmosphere except red light.
