The anode voltage of photocellis kept fixed. The wavelength lambda of the light falling on the cathode is gradually changed. The plate current I of the photocell varies as follows:

The stopping potential in a photoelectric experiment is linearly related to the inverse of the wavelength (1/lambda) of the light falling on the cathode. The potential difference applied across an X-ray tube is linearly related to the inverse of the cutoff wavelength (1/lambda) of the X-ray emitted. Show that the slopes of the lines in the two cases are equal and find its value.

The cathode and anode in a photocell are respectively.

In the experimental setup for a photocell, the wavelength of the light incident on the cathod is initially 0.6 times the threshold wavelength for the material of the cathode. Certain change in the experimental setup are given in column A and their possibel effects are given in column B. {:("Column A","Column B"),((i)"The intensity of the incident light is doubled but the frequency remains unaltered",(a)"Photocurrent remains the same"),((ii)"Both the intensity and wavelength of the incident light are doubled",(b)"Photcurrent falls to zero"),((iii)"The intensity of the incident light is doubled and its wavelength is made half",(c)"Stopping potential increase"),((iv)"The intensity of the incident light ramains the same and the wavelength is made half",(d) "Photocurrent increases"):}

The maximum kinetic energy of photoelectron is doubled when the wavelength of light incident on the photosensitive changes from lambda_1 to lambda_2 . Deduce expression for the threshold wavelength and work function for metals in terms of lambda_1 and lambda_2

If lambda_(0) is the threshold wavelength for photoelectric emission. lambda wavelength of light falling on the surface on the surface of metal, and m mass of electron. Then de Broglie wavelength of emitted electron is :-

If one angle of a triangle is kept fixed then the measure of the remaining two angles vary inversely with each other

A vacuum photocell consists of a central cathode and an anode. The internal surface is silver of work function 4.5 eV. The contact potential difference between the electrodes equals to 0.6 V. The photocell is illuminated by light of wavelength 2.3xx10^-7 m. a. What retrading potential difference should be applied between electrodes of the photocell for the photocurrent to drop to zero? b. If a retarding potential of 1V is applied between electrodes at what limiting wavelength lamda of light incident on the cathode will on the cathode will the photoelectric effect begin?
