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.
Which of the following is NOT a source of light?
eyes
lit candle
sun
firefly
Light is able to pass through __________________ materials
transparent
shiny
dull
opaque
Light is unable to pass through ________________ objects
opaque
coloured
blunt
dark
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
A transparent object that bends light into rainbow colors.
prism
mirror
convex lens
concave lens
Violet light is refracted the most by a glass prism as the light travels the ................ through the glass prism.
slowest
fastest
The substance in the sky which is involved in the formation of rainbow
Air particle
Dust
Raindrop
soot
What is a Spectrum?
A band of 7 colors
A group of 10 colors
A band of 10 colors
A mixture of 7 colors
After rainfall, a rainbow forms, ALWAYS or SOMETIMES or NEVER, Why?
Always, because the surface of the water droplet matters for the reflection, dispersion and refraction of the sun's white light.
Sometimes, because the surface of the water droplet matters for the reflection, dispersion and refraction of the sun's white light.
Never, because the surface of the water droplet matters for the reflection, dispersion and refraction of the sun's white light.
Rainbow is formed due to ................................
Natural dispersion
Sunlight passing through raindrops
Refraction of light
All of the above
