electron energy E =10eV
we have,
E=hc/l
where l is the wave length
10=(6.62x10^-34)(3x10^8)/l
l=19.86x10^-36/(10x1.6x10^-19)[10eV convert to joules ]
l=19.86x10^-18m
we have,
E=hc/l
where l is the wave length
10=(6.62x10^-34)(3x10^8)/l
l=19.86x10^-36/(10x1.6x10^-19)[10eV convert to joules ]
l=19.86x10^-18m
