"Violet scatters the most in the atmosphere but still the sky appears blue." Justify the given statement.

Solution

When white light from the sun passes through the earth's atmosphere, its different constituent colours scatter differently as they have different wavelegnths. Red colour scatters the least while the violet scatters the most. However, the sky still appears blue and not violet. This is because the sun emits a higher concentration of blue light waves in comparison to violet. Furthermore, as our eyes are more sensitive to blue rather than violet this means to us the sky appears blue.

Sir,

I am Shaun job of class 10, I have a doubt in physics on the topic of optics,

This is the question Sir

If the Rayleigh scattering holds good, then the intensity of scattering is inversely proportional to the fourth power of the wavelength, then when sunlight enters the earth's atmosphere, the violet light should get scattered the most and blue light also gets scattered, but less than violet light, so my question is why doesnt the sky appear violet instead of blue??

Thank you Sir

Shaun
