Why are the clouds blue?
On the electromagnetic visible spectrum, blue is the shortest wavelength, so blue scatters more than the other colors and makes the sky look blue. When light hits the water droplets in the clouds, all of the light is scattered equally. This color is reflected onto the clouds like a projector screen.
Can clouds be blue?
Green and Blue Clouds A cloud can look blue if it is heavily shaded and is illuminated by the scattered blue light of the blue sky. Probably the most unusual colour for a cloud is green. This is thought to be due to a cloud containing a large amount of water being back lit by reddish light, such as at sunset.
How are blue clouds formed?
The water in noctilucent clouds is either transported up into the mesosphere from the lower atmosphere, or forms when methane in the mesosphere breaks down by absorbing the sun’s rays. Ozone absorbs red light and allows blue light to pass through, which is why these clouds take on a striking blue colour.
Why is the sky blue at noon when no clouds are present?
The sky during the day At noon, when the Sun is overhead it appears white. This is because the light travels a shorter distance through the atmosphere to get to us; it’s scattered very little, even the blue light. During the day the sky looks blue because it’s the blue light that gets scattered the most.
Why is the Colour of the clear sky blue explain?
The Short Answer: Gases and particles in Earth’s atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.
Why sky is blue and clouds are white?
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.
What are blue clouds called?
Altostratus clouds are gray or blue-gray mid-level clouds composed of ice crystals and water droplets. The clouds usually cover the entire sky. Weather prediction: Be prepared for continuous rain or snow!
What is a blue Cloud?
Blue Cloud is an approach to shared infrastructure developed by IBM. The goal of IBM’s Blue Cloud is to provide services that automate fluctuating demands for IT resources. Blue Cloud makes use of virtualized Linux images and parallel workload scheduling.
