A number of identical absorbing plates are arranged in between a source of light and a photo cell. When there is no plate in between, the photo current is maximum. Under the circumstances let us focus on the two statements - (1) The photo current decreases with the increase in number of absorbing plates. (2) The stopping potential increases with the increase in number of absorbing plates.

Options

  1. AStatements (1) and (2) are both true and (1) is the cause of (2).
  2. BStatements (1) and (2) are both true but (1) and (2) are independent.
  3. CStatement (1) is true while (2) is not true and (1) and (2) are independent.
  4. DStatement (1) is true while (2) is not true and (2) is the effect of (1).

Correct answer

C. Statement (1) is true while (2) is not true and (1) and (2) are independent.

Ultraviolet light of wavelength 300 nm and intensity 1 ~W / m ^2 falls on the surface of a photosensitive material. If one percent of the incident photons produce photoelectrons thIn an X ray tube the electrons are expected to strike the target with a velocity that is 10 % of the velocity of light. The applied voltage should beWhich of the following curves represents spectral distribution of energy of black body radiation?The force of attraction between the positively charged nucleus and the electron in a hydrogen atom is given by f=k e^2 r^2 . Assume that the nucleus is fixed. The electron, initialThe photoelectric threshold wavelength of tungsten is 230 nm .
