Step-by-step solution

I As sunlight enters the Earth's atmosphere, all the gas molecules and dust in the atmosphere scatter the white light in every direction. Since blue light moves as shorter, smaller waves it scatters more than other colours. Thus, the blue colour of the sky is due to the scattering of light. II As light strikes the diamond, it refracts within the lattice and flows through it. At different angles, total internal reflection happens, and the light gradually refracts out. The diamond's shape causes light to stri
