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 while violet 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 substance in the sky which is involved in the formation of rainbow
Air particle
Dust
Raindrop
soot
Why the sky look blue during midday and red during sunset
Reflection of light
Refraction of light
Dispersion of Light
Scattering of Light
Why does scattering of light occur?
Light rays are blocked and reflected to all directions by the clouds or particles in the air
Light rays are blocked and refracted to all directions by the clouds or particles in the air
Light rays are passing through and refracted to all directions by the clouds or particles in the air

the longest
short
the fastest
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.
If the atmosphere is polluted with more dust and smoke, the sunset looks more ......
yellowish or redness
blue and indigo
purple and red
black
The color of light that is less scattered is .......
indigo
blue
red
white
Blue colour is scattered _______ compared to the ______ colour.
sunset, more, yellow
sunset, less, red
the day, more, yellow
the day, less, yellow
Only allow the light of the same colour to pass through, light of other colours are absorbed.

red
green
Which two filters could be combined to make a white light appear red?
blue
cyan
magenta
yellow
green
How does light behave when hitting this shirt?
Yellow is absorbed; all other colors are reflected.
Yellow is reflected; all other colors are absorbed.
All colors are absorbed, but yellow is refracted.
Yellow is scattered and all other colors are absorbed.
Which color will transmit through the filter?
Red only
Blue and Violet
Green
All colors
Magenta light is a mix of which two colours?
red
green
blue
Which pair of colours do NOT combine to make the correct secondary colours?
Red + Blue = Magenta

Red + Yellow = Green
Why does this the t-shirt appear red and the shorts appear blue? Choose the correct statements.
The t-shirt reflects red light.
The t-shirt reflects blue light
The shorts absorb yellow light
The shorts reflect blue light
Other colours are absorbed
Why do a magenta filter and a yellow filter produce two coloured light?
They allow only one wavelength (colour) of light to pass through.
They allow primary colours of light to pass through.
The filters separate the primary colours which make up the secondary colours (magenta & yellow).
In the additive colour mixing, select the secondary colours.
Yellow
White
Magenta
Cyan
Which colour combinations produce yellow?
Red and Cyan
Cyan and Magenta
Red and Blue
Red and Green
