Q. Which of the following phenomena accounts for the blue appearance of the sky on a clear day?
✅ Correct Answer: (B)
Rayleigh scattering
Explanation: Rayleigh scattering refers to the scattering of light by particles much smaller than the wavelength of the light. Because shorter wavelengths (blue and violet) scatter much more efficiently than longer wavelengths (red), the sky appears blue.
