Worksheets8.5 DISPERSION OF LIGHT
Total questions: 16
Worksheet time: 8mins
These are all colours of the spectrum except for
indigo
purple
blue
green
An example of disperion of light
Rainbow
Shadow
Sky looks bright orange in the evening
Pool seems shallower
Why cant we see a spectrum of colours when white light pass through a glass prism?
phenomenon of scattering of light
phenomenon of reflection of light
phenomenon of dispersion of light
phenomenon of diffraction of light
Why is the red light is at the top and violet light at the bottom of the spectrum?
Violet light has the medium speed so it is refracted the least
Red light has the lowest speed so its refracted the least
Violet light has the highest speed so its refracted the least
Red light has the highest speed so it is refracted the least
How are colours of the rainbow formed?
from the sun hitting the water
from light hitting objects
through diffrent wavelenghts of refracted light
If u see the rainbow but not the sun,the sun should be positioned
infront of you
behind you
on your left side
on your right side
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 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
The substance in the sky which is involved in the formation of rainbow
Air particle
Dust
Raindrop
soot
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
