Would 449-nm blue light eject electrons from silver metal with a work function of 4.74 eV?
E = hc/lamba
The Attempt at a Solution
E = [(6.63*10^-34 J*s)(3.00*10^8 m/s)]/(4.49*10^-7 m)
= 4.42*10^-19 J
= 2.77 eV
Since 2.77 eV is less than the work function the blue light would not eject electrons from the silver metal.
***is this correct?? thanks for the help in advance! :)
