A point source of light is used in a photoelectric effect. If the source is moved farther from the emitted metal, the stopping potential

A

will increases

B

will decreases

C

will remains constant

D

will either increases or decreases

Text Solution

Verified by Experts

The correct Answer is:
C
Stopping potential depends on the K.E. of emitted electron. The K.E. of emitted electron depends on the frequency of the photon, not the intensity of the photon

A point source of light is used in an experiment on photoelectric effect . Which of the following curves best represents the variation of photo current (i) with distance (d) of the source from the emitter ?

Light of wavelength 488 nm is produced by an argon laser which is used in the photoelectric effect. When light from this spectral line is incident on the emitter, the stopping (cut - off) potential of photoelectrons is 0.38 V. Find the work function of the material from which the emitter is made.

In a photoelectric effect , the K.E. of electrons emitted from the metal surface depends upon

A non-monochromatic light is used in an experiment on photoelectric effect. The stopping potential

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. A monochromatic light is used in a photoelectric experiment on photoelectric effect. The stopping potential

A point source of light is taken away from the experimental setup of photoelectric effect. For this situation, mark out the correct statement (s).

when a monochromatic point source of light is at a distance 0.2 m from a photoelectric cell, the saturation current and cut-off voltage are 12.0 mA and 0.5 V. If the same source is placed 0.4 m away from the photoelectric cell, then the saturation current and the stopping potential respectively are
