Physics
Please help me with this problem. The standard source for radiation therapy was radioactive 60Co which decays with a halflife of 5.27y, into an excited nuclear state of 60Ni. That nickel isotope then immediately emits two gamma ray photos wach with energy of 1.2 MeV. How many ...

Does work function=hc divided by initial wavelength. What would the initial wavelength be? 4x10E-7 nm?

physics
What is the minimum work function for a metal for visible light (wavelengths between 400 and 700 ) to eject photoelectrons?
