Calculate the frequency and kinetic energy of emitted electrons for given wavelength of incident light and work function of the metal.

Here are the solutions to your physics problems.

Question 1:
Given:
Wavelength of incident light $\lambda = 5.00 \times 10^{-7}$ m
Work function of the metal $W_0 = 3.0 \times 10^{-19}$ J

Constants:
Speed of light $c = 3.00 \times 10^8$ m/s
Planck's constant $h = 6.626 \times 10^{-34}$ J$\cdot$s
Charge of an electron $e = 1.602 \times 10^{-19}$ C

*1) Frequency of
