Final answer:
The maximum kinetic energy of the emitted photoelectrons depends on the frequency or wavelength of the incident light. It can be calculated using the equation KE = hf - BE, where KE is the kinetic energy, h is Planck's constant, f is the frequency (speed of light divided by the wavelength), and BE is the binding energy. However, in this question, only the maximum electron kinetic energy is provided, so we can't directly calculate the wavelength.
Step-by-step explanation:
The maximum kinetic energy of the emitted photoelectrons depends on the frequency or wavelength of the incident light. It can be calculated using the equation KE = hf - BE, where KE is the kinetic energy, h is Planck's constant, f is the frequency (speed of light divided by the wavelength), and BE is the binding energy. However, in this question, only the maximum electron kinetic energy is provided, so we can't directly calculate the wavelength. We can use the concept of energy conservation to find the maximum kinetic energy for a different wavelength.
Since the work function (binding energy) of the metal is not given, we cannot determine the exact value of the maximum electron kinetic energy when illuminated by light with a wavelength of 350 nm. The work function determines the minimum energy (or wavelength) required to eject an electron. Without knowing the work function, we cannot calculate the maximum kinetic energy. However, we can say that if the wavelength decreases from 450 nm to 350 nm, the kinetic energy of the emitted electrons is expected to increase because shorter wavelengths have higher energy photons.
