Answer 1

Correct Answer - Option 3 : Colourless light

The correct answer is Colourless light.

 

• Rainbow is caused by the total internal reflection, refraction, and dispersion of the light.
• If we mix lights of the colours of the rainbow, we will get colourless light.
• White colour reflects all other colours.
• White colour is the colour which absorbs minimum heat.
• There are seven colours in the rainbow.
• The colour which appears on the upper portion of the rainbow is red.
• The colour which appears on the lowest portion of the rainbow is violet.
• Rainbow is always formed in the opposite direction of the Sun.

• Red, blue, and green are called primary colours.
• Yellow, Magenta, and Cyan are called secondary colours.
• If we mix green and red we will get Yellow colour.
• If we mix blue and red we will get Magenta colour.
• If we mix green and blue we will get Cyan colour.
