The energy in one quantum of UV light is 4.14 eV.
The energy in one quantum is calculated as,
[tex]E=h \nu[/tex]
Where h is planks constant and [tex]\nu[/tex] is frequency.
Value of [tex]h=6.626*10^{-34}Joule/Hz[/tex]
Given that, [tex]\nu=1*10^{15} Hz[/tex]
Substitute all values in above equation
[tex]E=6.626*10^{-34}*10^{15}=6.626*10^{-19}Joules\\ \\ E= \frac{6.626*10^{-19}}{1.6*10^{-19} }=4.14eV[/tex]
