In photoelectric effect, stopping potential depends on

A

frequency of the incident light

B

intensity of the incident light by varies surce distance

C

emitter's properties

D

frequency and intensity of the incident light

Text Solution

Verified by Experts

The correct Answer is:
A, C
`hv = hv_(0) + eV_(s) , V_(s) = ((hv - hv_(0)))/(e) , eV_(s) = hv - phi`
Here `v=` frequency of incident light and `phi =` properties of emitter

In an experiment on photoelectric effect, the stopping potential is measured for monochromatic light beams corresponding to different wavelength. The data collected are as follows: wavelength (nm): 350 400 450 500 550 stopping potential (V): 1.45 1.00 0.66 0.38 0.16 Plot the stopping potential against inverse of wavelength on a graph paper and find (a) the Planck constant, (b) the work function of the emitter and (c) the threshold wavelength .

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

In a photoelectric experiment, if stopping potential is applied, then photocurrent becomes zero. This means that:

In a photoelectric effect experiment, stopping potential changes by 30 volt if we change frequency of the radiation. Then the magnitude of change in the frequency is : (h=6xx10^(-34) J-s)

By photoelectric effect, Einstein, proved

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
