Question

What is dispersion? Write seven colours of sunlight.​

Answer 1

Answer:

The sun's rays are actually white in colour and form a mixture of the seven colours we see in a rainbow, i.e., Violet, Indigo, Blue, Green, Yellow, Orange, and Red, commonly called VIBGYOR. The sun appears to have different colours during the course of a day because of a process called dispersion.

Answer 2

Required Answer:-

⟶ Dispersion of light is the phenomena of scattering of a white light into seven colours when passed through a glass prism.

The seven colours present in the sunlight are:-

• Red
• Orange
• Yellow
• Green
• Blue
• Indigo
• Violet

We can also say these as, VIBGYOR.

These seven colours which scatter from a glass prism are also known as spectrum of light.

________________________________

Extra Information:-

• Among these seven colours, red has the greater wavelength.
• Among these seven colours, violet has the least wavelength.
• The colour with high wavelength has more tendency to move particles from their path.
• The colour with least wavelength scatter away on collapsing with particles.
• The colour which bends the least after scattering through a glass prism, has the highest wavelength.
• The colour which bends the most after scattering through the glass prism, has the least wavelength.
