(ii) intensity of the incident radiation.

A

both (i) and (ii) are correct

B

only (i) is correct

C

only (ii) is correct

D

neigher (i) nor (ii) is correct.

The stopping potential for acertain photosensitive metal is Vq when the frequency of incident radiation is V_(0) When the frequency of the incident radiations is doubled, what will be the stopping potential ?

When a high frequency electromagnetic radiation is incident on a metallic surface, electrons are emitted from the surface. Energy of emitted photoelectrons depends only on the frequency of incident electromagnetic radiation and the number of emitted electrons depends only on the intensity of incident light. Einstein's protoelectron equation [K_(max)=hv-phi] correctly ecplains the PE, where upsilon= frequency of incident light and phi= work function. Q. For photoelectric effect in a metal, the graph of the stopping potential V_0 (in volt) versus frequency upsilon (in hertz) of the incident radiation is shown in Fig. The work function of the metal (in eV) is.

The graph of Fig. shows the variation of photoelectric current (I) versus applied voltage (V) for the two different photosensitive materials for two different intensities of the incident radiation. Identify the pairs of curves that correspond to different materials but same intensity of incident radiation.

In the photoelectric effect experiment, if f is the frequency of radiation incident on the metal surface and I is the intensity of the intensity radiations, then match the following columns:

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

What is photoelectric effect? Explain experimentally the variation of photoelectric current with (i) the intensity of the incident light (ii) the potential difference between the plates and (iii) the frequency of the incident light and hence state the laws of photoelectric emission.

Does the stopping potential in photoelectric emission depend upon the intensity of the incident radiation in a photo cell? Comment on it.

How does kinetic energy of ejected photoelectrons depend upon the frequency of incident radiation?
