To determine whether the statement "In a photoelectric emission process, the maximum energy of the photo-electrons increases with increasing intensity of the incident light" is true or false, we can analyze the situation using the principles of the photoelectric effect. ### Step-by-Step Solution: 1. **Understanding the Photoelectric Effect**: The photoelectric effect occurs when light (photons) strikes a metal surface and causes the emission of electrons. The energy of the emitted electrons depends on the energy of the incident photons. 2. **Einstein's Photoelectric Equation**: ...

In an experiment of photo-electric effect, the graph of maximum kinetic energy E_(k) of the emitted photoelectrons versus the frequency v of the incident light is a straight line AB as shown in figure below : Work function of the metal.

In an experiment of photo-electric effect, the graph of maximum kinetic energy E_(k) of the emitted photoelectrons versus the frequency v of the incident light is a straight line AB as shown in figure below : Threshold frequency of the metal.

When light of sufficiently high frequency is incident on a metallic surface, electrons are emitted from the metallic surface. This phenomenon is called photoelectric emission. Kinetic energy of the emitted photoelectrons depends on the wavelength of incident light and is independent of the intensity of light. Number of emitted photoelectrons depends on intensity. (hv-phi) is the maximum kinetic energy of emitted photoelectron (where phi is the work function of metallic surface). Reverse effect of photo emission produces X-ray. X-ray is not deflected by electric and magnetic fields. Wavelength of a continuous X-ray depends on potential difference across the tuve. Wavelength of charasteristic X-ray depends on the atomic number. Q. If potential difference across the tube is increased then

Explain giving reasons for the following : (a) Photoelectric current in a photocell increases with the increase in intensity of the incident radiation. (b) The stopping potential V_0 varies linearly with the frequency nu 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.
