What characteristic property of light is responsible for the blue colour of the sky?
- A. Interference
- B. Diffraction
- C. scattering
- D. Dispersion
Step-by-step solution
The blue colour of the sky is due to Rayleigh scattering of sunlight by the Earth's atmosphere. Shorter wavelengths (blue) are scattered more than longer wavelengths, making the sky appear blue.
