Question

Use these data to make a plot like Fig. 38-2 (which is for sodium)and then use the plot to find (a) the Planck constant and (b) the work function for lithium.

$λhc =KE_{max}+ϕ_{o}$

$λhc =eV+ϕ_{o}$

$V=eλhc −eϕ_{o} $

From the graph we find, $h=6.626×10_{−34}Jsec$

{b} $W$ ( work function ) = $λhc =2.3eV$
