(a)
An arrangement for observing the scattering of light in a colloidal solution to show how the sky appears blue, and the sun appears red at sunrise and sunset.
(b) Blue light scatters more easily due to its smaller wavelength.
(c) Shortest wavelength component i.e. blue scatters away when the sun appears red at sunrise or sunset.
(d) Gas molecules present in the air.
