Question

In a photoelectric experiment, the wavelength of incident photons is and the maximum speed of photoelectron emitted is v. If the wavelength of incident radiation is changed to , then the maximum speed of emitted photoelectron will be

Answer 1

Answer:

So if wavelength of incoming light increases (its associated frequency decreases) therefore the ejected electron will have a lower velocity as well. Until the wavelength is increased such that the associated light frequency fall below the threshold for that material, in which case the electron velocity will be zero.
