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

The path of a beam of light passing through a true solution is not visible. However, its path becomes visible through a colloidal solution where the size of the particles is relati

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

The blue light due to its short wavelength is scattered more than the red light of long wavelength. Thus the light directly from the sun reaching our eye is rich in red colour whil

23. Why is the colour of the clear sky blue? Soln: Blue is the colour in the visible spectrum which is having maximum scattering. This makes the blue colour to reach us and the sky

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

Why do the stars twinkle? As a star’s light penetrates the Earth’s atmosphere, every individual stream of starlight is refracted – caused to change direction, slightly – by

Why are clouds white? 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

The short-wavelength blue and violet are scattered more than colours of the lower end of the spectrum which are less easily scattered. Noon If the sun is overhead in the sky, the r

On Earth, the sky appears blue to us because the tiny particles present in the atmosphere scatter the blue colour from the incoming sunlight. However, when an astronaut is in outer
