Question

Hey BRAINLIACS

SUBJECT-PHYSICS (CLASS 10)

Plz answer my these 2 questions..

1)Why does clouds appear white?(EXPLAIN)
2)Why sky appears grey in industrial areas?(EXPLAIN)

NO SPAMMING PLZ

Answer 1

Unlike scattering in the sky or ocean, in which molecules are so small they only scatter blue and violet light, water droplets are large enough the scatter the entire spectrum. That's why clouds appear to be mostly white.

rain clouds are gray instead of white because of their thickness, or height. That is, a cloud gets thicker and denser as it gathers more water droplets and ice crystals — the thicker it gets, the more light it scatters, resulting in less light penetrating all the way through it.

Answer 2

1)the sky appears to be white in noon time
the blue light is having minimum wavelength so it is scattered so sky the sky appears to be blue
the clouds appear to be white because the water droplets (which are evaporated from Earth surface) join together to form clouds
most of the colours( usually blue) and the tiny particles of the sky also scatter to all colours of light together make up the white colour

so the clouds appear to be white colour

2) in some days the sky appears to be grey or white because in the sky many particles are present as a result the particles get scattered
having the different wavelengths so as a result we can see the change in the colour of the sky
like blue ,white and grey and etccccc
