A light wave has a frequency of 4xx10^(14)Hz and wavelength on a water [n_(w)=(4)/(3)] interface. The critical angle of incidence is ___________. |

Answer» Solution :Here `v=4xx10^(14)Hz and lambda=500 nm =5xx10^(-7)m` `RARR""v=upskon lambda=4xx10^(14)xx5xx10^(-7)=2xx10^(8)MS^(-1)` `rArr""N=(c)/(v)=(3xx10^(8))/(2xx10^(8))=1.5` |
