Question

If the work function of a metal is increased, what happens to the minimum frequency of light required to eject an electron from the metal? The minimum frequency increases. The minimum frequency depends on the intensity of the light. The minimum frequency remains the same. The minimum frequency decreases.

Step 1

Step 1: Use the photoelectric (Einstein) equation: KE_max = hf - φ, where KE_max is the maximum kinetic energy of an ejected electron, h is Planck's constant, f is the light frequency, and φ is the work function. Show more…
