On the homework for problem 1B.15, the equation gives the velocity of the photon. I used the velocity to find the kinetic energy of the photon. However, the problem asks me to find the wavelength. But, there is no given work function or energy of the photon. How am I suppose to solve for the wavelength?
Given the velocity of the photon, we can use De Broglie's Equation: . We know the values for Planck's constant (6.626 x 10-34 Js) and for the mass of an electron (9.109 x 10-31 kg). Since we are given the velocity, we can just solve for wavelength.
