2. 3. 4. What do you mean by stopping potential with respect to photoelectric effect [5] experiment? The work function of tungsten is 4.53eV. If ultraviolet light of wavelength 1500A is incident on the surface, does it cause photoelectron emission? If so, what is the kinetic energy of the emitted electron. State the Heisenberg's uncertainty principle. An electron is accelerated through [5] a potential difference of 182 volts. Calculate the de Broglie wavelength of the electron. State the physical admissibility conditions of a wave function representing a [5] material particle. An electron is confined to move in a one-dimensional potential box of length 5Å. Find the quantized energy values of the ground state and first excited energy state.
