Why is the sky blue and how can we conduct an experiment to understand this phenomenon better?

The sky appears blue because of a phenomenon called Rayleigh scattering, where shorter blue wavelengths of light are scattered more by the Earth's atmosphere. To conduct an experiment to understand this better, one can use a prism to separate white light into its different colors and observe how blue light scatters more than other colors. Additionally, one can use a spectrophotometer to measure the amount of blue light scattered at different angles in the sky.
