What are thunder clouds called?

Cumulonimbus clouds

Do black clouds exist?

For decades medical residents have put themselves into two camps: “black clouds” and “white clouds.” Black-cloud residents carry with them the bad luck of consistently getting a patient load that requires more work; the perceived workload intensity and stress may keep them pacing the halls at night, while their white- …

Why do black clouds only rain?

White is how our eyes perceive all wavelengths of sunlight mixed together. When it’s about to rain, clouds darken because the water vapor is clumping together into raindrops, leaving larger spaces between drops of water. Less light is reflected. The rain cloud appears black or gray.

Why are clouds white in 10th?

Clouds are white because light from the Sun is white. But in a cloud, sunlight is scattered by much larger water droplets. These scatter all colours almost equally meaning that the sunlight continues to remain white and so making the clouds appear white against the background of the blue sky.

Why is the sky blue in Class 10?

Scattering of light is the phenomenon that causes the sky to appear blue. Fine dust in the earth’s atmosphere scatters the sunlight. Out of all the constituent colours of sunlight, blue colour is scattered the most. Thus, the sky appears blue to us.

Why do sky looks blue?

The sky is blue due to a phenomenon called Raleigh scattering. This scattering refers to the scattering of electromagnetic radiation (of which light is a form) by particles of a much smaller wavelength. These shorter wavelengths correspond to blue hues, hence why when we look at the sky, we see it as blue.

Why is clear sky blue?

The Short Answer: Sunlight reaches Earth’s atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered more than the other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

Is our sun blue?

So one might say that the sun is blue-green! This maximum radiation frequency is governed by the sun’s surface temperature, around 5,800K. Because though the sun emits strongest in the green part of the spectrum, it also emits strongly in all the visible colors – red through blue (400nm to 600nm).

Is the star hotter than the sun?

NO. The hottest stars have surface temperatures of 50,000 Kelvin degrees. The Sun surface is only 5800 Kelvin degrees, which means that there are hotter starts than the Sun.
