Question

Q.6) Calculate the maximum kinetic energy of electrons emitted from photosensitive surface of work function 3.2 eV, for the incident radiation of wavelength 300 nm.

Answer 1

We know,

E= WORK FUNC. + K.E.

E= hc/Wavelength = 3.2+ K.E.

E= 6.6*10^-34*3*10^8/ 300*10^9m = 3.2 +K.E

E= 1.98/300 = 3.2+ K.e

K.E.= 0.0066 - 3.2

K.E. = 3 .2 J

There are Calculation Errors !! Lol!!

But, I hope the concept helpsz!!;
