Calculate the wavelength of this light in nm
Homework Answers
light of frequency 1.30x 1015 s-1
maximum kinetic energy of 5.2x 10-19 J.
maximum kinetic energy, donot bother because, workfunction is involved in this
hμ - workfunction = maxm KE
this light μ= 1.30x 1015 s-1
λ= 2.307*10^(-7)
= 230.7nm.
