Question

What is the effect on the velocity of the emitted photoelectron on decreasing the wavelength of incident light

Answer 1

there will be an increase in the velocity

Answer 2

Hey mate here is your answer ★★★★ :—

★} Then the answer is as follows: as the incident radiation wavelength increases, the energy per photon DECREASES. The photon energy, less the threshold energy, is the KE of the fastest emitted electrons. As the incident energy is decreased, the KE will decrease and the velocity would decrease.

★} yes there is a chance of increasein velocity.

hope it helps you Mate .★_★
