Answer:
[tex]\lambda=2.61\times 10^{-9}\ m[/tex] = 261 nm
Silver is not a good choice.
Explanation:
[tex]E=\frac {h\times c}{\lambda}[/tex]
Where,
h is Plank's constant having value [tex]6.626\times 10^{-34}\ Js[/tex]
c is the speed of light having value [tex]3\times 10^8\ m/s[/tex]
[tex]\lambda[/tex] is the wavelength of the light
Given that:- Energy = [tex]7.59\times 10^{-19}\ J[/tex]
[tex]7.59\times 10^{-19}=\frac{6.626\times 10^{-34}\times 3\times 10^8}{\lambda}[/tex]
[tex]7.59\times \:10^{26}\times \lambda=1.99\times 10^{20}[/tex]
[tex]\lambda=2.61\times 10^{-9}\ m[/tex] = 261 nm
Visible range has a spectrum of 380 to 740 nm
So, Silver is not a good choice.
