The colour of the clear sky is blue due to the phenomenon of:

dispersion of light

reflection of light

scattering of light

refraction of light

Sure, let's explore the options:

- Option 1: Dispersion of light

- Dispersion occurs when white light splits into its component colors, like in a prism.

- It is not responsible for the blue sky.

- Option 2: Reflection of light

- Reflection involves light bouncing off surfaces.

- Not the cause of the sky's color.

- Option 3: Scattering of light

- Scattering happens when particles or molecules spread light in different directions.

- The sky appears blue due to Rayleigh scattering, where shorter (blue) wavelengths scatter more than longer (red) ones.

- Option 4: Refraction of light

- Refraction is the bending of light as it passes through different media.

- Also not the reason for blue skies.
