A total 75µm of light with a wavelength of 376nm strikes a platinum plate. For platinum the woek function ?= 6.8eV

a) what is the energy of electrons ejected from this surface by this light ? What will their velocity be ?

b) If 5.7mJ of light were used instead, how would this experimental result change?

c) If 230nm wavelength light were used instead still 75µm what changes would be there compared to part (a)? Looking at the number and the energy of the electron
