Scattering of light - BYJUS 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 phenomenon is known as the Mie effect Due to the largeness of particles, the light appears white That is why the clouds, which are made of water droplets, are white

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 relatively larger The topic further discusses the Tyndall Effect – why the colour of the clear sky is blue, and the colour of the Sun at sunrise and sunset
In the meter bridge experiment,balance point was observed J . . . - Toppr In the meter bridge experiment,balance point was observed at J with AJ=I i) The values of R and X were doubled and then interchanged What would be the new position of balance point? ii) If the galvanomater and battery are interchanged at the balance position,how will the balance point get-affected?
BYJUS Online learning Programs For K3, K10, K12, NEET, JEE, UPSC . . . 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 by the atmospheric particles In the spectrum of white light, blue is the colour that has a minimum wavelength Hence, the blue colour scatters the most and is scattered in all directions by the tiny atmospheric
BYJUS Online learning Programs For K3, K10, K12, NEET, JEE, UPSC . . . 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 while the light from all the other directions reaching our eye is the scattered blue light Therefore the sky in the direction of the sun is 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 appears blue 24 What is the difference in colours of the Sun observed during sunrise sunset and noon?
