Question

The sunlight which reaches earth is yellowish, rather than white. It is because due to scattering, the sunlight is deficient in:
A) violet colour
B) indigo colour
C) blue colour
D) violet, indigo and blue colour​

Answer 1

D) violet, indigo, and blue color​ is the correct answer to the given question.

• As we know that sunlight is actually light waves of different frequencies.
• With lower frequencies, light waves appear more red or orange.
• And with higher frequency light waves appear violet, indigo, or blue.
• The particles in the air scatter the light waves of higher frequencies when the sunlight shines down through the atmosphere.
• Therefore the sunlight which reaches the earth is yellowish. It is because due to scattering, the sunlight is deficient in violet, indigo, and blue color.

Answer 2

Answer:

D) violet, indigo and blue colour​

Explanation:

• As we all know, sunlight is made up of light waves of various frequencies. Light waves appear more red or orange at lower frequency. Light waves of higher frequency appear violet, indigo, or blue. When sunlight shines down through the atmosphere, the particles in the air disperse higher frequency light waves.
• As a result, the sunlight that reaches the earth is yellowish in colour. It's because sunlight is lacking in violet, indigo, and blue colors due to dispersion.
