AI Generated Solution

To solve the problem, we will use the photoelectric effect equation, which relates the energy of the incident photons to the work function of the material and the kinetic energy of the emitted photoelectrons. ### Step-by-Step Solution: 1. **Understand the Photoelectric Effect Equation**: The photoelectric effect is described by the equation: \[ E = h \nu = W_0 + KE ...

    Explain giving reasons for the following: (a) Photoelectric current in a photocell increases with the increase in the intensity of the incident radiation. (b) The stopping potential (V_(0)) varies linearly with the frequency (v) of the incident radiation for a given photosensitive surface with the slope remaining the same for different surfaces. (c) Maximum kinetic energy of the photoelectrons is independent of the intensity of incident radiation.

    When the frequency of the incident radiation on a metallic plate is doubled, KE of the photoelectrons will be
