1. The light rays from the sun and artificial lights, are all light rays made up of 'photons' which travel in the form of waves? 2. During a sunstorm, when the Auroras form in the ionosphere by electrons colliding with atomic o2 and atomic nitrogen, can these electrons be thought of as 'Beta Rays'? 3. When a beam of white light is diffracted in a grating and dispersed into its component colours, do all these photons of light have the same energies yea?
