Calculate the frequency and energy per quantum of a radiation with a wavelength of 200 nm. `(c = 3 xx 10^(8) ms^(-1)` and `h = 6.625 xx 10^(-34)`Js)

Text Solution

Verified by Experts

`v=c/lamda=(3xx10^(8)ms^(-1))/(200xx10^(-9)m)=1.5xx10^(15)Hz=1.5xx10^(15)Hz`
`E=hv=6.6252xx10^(-34)xx1.5xx10^(15)=9.9375xx10^(-19)J`
