Answer:
Required wavelength of light is 85.6 nm.
Explanation:
E = h×ν = [tex]\frac{hc}{\lambda}[/tex]
E = Energy in J
ν = frequency (Hz s-1)
λ = wavelength in m
Planck constant h = J s
c = speed of light = m s-1
2.32 aJ = J
E = h×ν
[tex]\lambda = \frac{2.998\times10^{8}}{3.50\times10^{15}}=8.56\times10^{-8} m = 85.6 nm[/tex]
