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. NCERT Solutions for Class 10 Science Chapter 11: The Human Eye
Why does the sky appear blue?
When a white light (from sun) enters the earth''s atmosphere, it gets scattered away due to the atmospheric particles. Since, blue colour has the minimum wavelength, so blue colour scatters the
What is the Tyndall Effect?
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 reason why the smoke released
Why Do Stars Twinkle?
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''s atmosphere. When

Scattering of light
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
