Homework Statement
Electrons are emitted from a metal as a consequence of their absorption of energy from a light beam. Find the threshold frequency of the metal and the wavelength of emitted electrons.
Wavelength of incident light λ = 500 nm
Work function of the metal [itex]\phi[/itex] = 2.1 eV
Homework Equations
Threshold frequency:
f0 = [itex]\frac{\phi}{h}[/itex]
The Attempt at a Solution
Threshold frequency:
f0 = [itex]\frac{2.1 eV}{4.136 \times 10^{-15} eV·s }[/itex] = 5.08 × 1014 Hz
Is this correct?
How can I find the wavelength of emitted electrons?
