Why Is the Colour of the Clear Sky Blue? And Why Are the Clouds White? Molecules with a larger size than the wavelength of light experience the scattering effect differently; the p

Why Does the Sunlight Appear Red, Orange or Yellow? When the sun rays enter the earth, they get distorted by the earth’s atmosphere including air molecules, dust and smoke. We kn

Blue Sky It is normal to say that the sky appears blue in colour. Have you ever thought about why it appears blue? When sunlight enters the Earth’s atmosphere, it gets scattered

Atmospheric optics is the scientific study and explanation of the unique and stunning optical effects in the sky. It encompasses the principles of physics that help answer common q

Generally, blue light is scattered to a greater extent when compared to red light. This is because the wavelength of blue light is smaller than that of red light. This is the reaso

Assertion :Bluish colour predominates in a clear sky, since blue has a shorter wavelength and is scattered strongly. Reason: Blue has the shortest wavelength among all colours.

Explain giving reason why the sky appears blue to an observer from the surface of the Earth. What should the appearance of the sky be during the day for an astronaut staying in the

The molecules of air and other fine particles in the atmosphere have size smaller than the wavelength of visible light. These are more effective in scattering light of shorter wave

Did you know that stars do not twinkle; they only appear to twinkle when seen from the Earth’s surface. The stars seem to twinkle in the night sky due to the effects of the Earth

Why Photographers Photos Have Vibrant Sky? The scattering of partially polarised light produces glare in the sky! This challenges the photographer to take the good vibrant photogra
