On what factor does the colour of scattered light depend upon?

Correct option is C

The correct answer is (c) The size of the scattering particles.
· The color of scattered light primarily depends on the size of the scattering particles. According to Rayleigh scattering, smaller particles scatter shorter wavelengths (like blue and violet light) more effectively, which is why the sky appears blue. In contrast, larger particles scatter all wavelengths more equally, leading to white or less color-specific scattering.
Information Booster:
· The color of the scattering particles: The particles themselves are usually too small to impart their color, especially in atmospheric scattering.
· The refractive index of the particles: This affects the bending of light rather than the color of the scattered light.
· The amount of impurity: Impurities might affect scattering but are not the primary factor determining the color of scattered light.
