Homework Statement
Homework Equations
E=hc/lamda
The Attempt at a Solution
I can get the amount of energy incident on the surface (3%of Intensity×Area)
What will be the energy required to make 1 electron escape?
(4.5eV+hc/250nm )?
Then I divide total energy by energy to make 1 electron escape.
Unfortunately,the calc gives the answer to be 2×10^10
Which ain't in the options..
Help appreciated.
