Explanation: When light ray emerges from the prism, it travels from denser to rarer medium. Based on the rule of refraction, it can bend from the normal. As a result, angle of refraction will likely be more than angle of incidence at that surface.
Lack of an electron from an atom brings about the formation of the cation. A cation is smaller sized than its mum or dad atom since it has fomer electrons while its nuclear demand remains a similar. For instance, The atomic radius of sodium (Na) is 186 pm and atomic radius of sodium ion (Na+) = ninety five pm.
