The vapours of Hg absord some electron accelerated by a potiential diff. of 4.5 volt as a result of which light is emitted . If the full energy of single incident e^(-) is supposed to be converted into light emitted by single Hg atom , find the wave no. of the light

Assertion: A photosensitive surface is illuminated by a monochromatic light of wavelength lambda and intensity I. The number of photoelectrons emitted per second is doubled when the intensity of light is doubled. However, the maximum speed of emitted electrons remains unchanged. Reason: The number of electrons emitted per second is directly proportional to the intensity of the incident light. The kinetic energy of the emitted photoelectrons is independent of the intensity of the light.

A mixture of hydrogen atoms (in their ground state) and hydrogen like ions (in their first excited state) are being excited by electrons which have been accelerated by same potential of emitted light are found in the ratio 5:1. Then, find (a) the minimum value of V for which both the atoms get excited after collision with electrons. (b) atomic number of other ion. (c ) the energy of emitted light.

When an electron is an excited hydrogen atom, jumps from n = 4 to n= 2 level, green light is emitted . Which colour of light will be observed, if the electron jumps from n=6 to n=2 ?

In a photoelectric experiment a parallel beam of monochromatic light with power of 200 is incident on a perfectly absorbing cathode of work function 6.25. The frequency of light is just above the threshold frequency so that the photoelectrons are emitted with negligible kinetic energy. Assume that the photoelectron emission efficiency is 100%. A potential difference of 500 is applied between the cathode and the anode. All the emitted electrons are incident normally on the anode and are absorbed. The anode experiences a force 10 due to the impact of the electrons. The value of is __________. Mass of the electron 910 and 1.01.610.

What is the wavelength of light emitted when the electron in a hydrogen atom undergoes transition from the energy level with n=4 to the energy level with n=1 ?

(a) The work function for the surface of aluminium is 4.2eV. Find potential difference will be required to stop the emission of maximum kinetic energy photoelectrons emitted by light of 1800Å wavelenght? (b) Determine the wavelength of that incident light for which stopping potential will be zero? (h=6.6xx10^(-34))

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 frequency (upsilongtupsilon_0) of incident light becomes n times the initial frequency (v), then KE of the emitted photoelectrons becomes ( v_0 threshold frequency).
