The stopping potential `(V_(0))`
(A) Depends upon the angle of incident light
(B) Depends upon the intensity of incident light
(C) Depends upon the surface nature of the substance
(D) Is independent of the intensity

Define critical angle. How does it depend on the wavelength of incident light?

Assertion: Stopping potential depends upon the frequency of incident light but is independent of the intensity of the light. Reason :The maximum kinetic energy of the photoclectrons is proportional to stopping potential

Is the measure of an angle dependent upon the unit of length ?

Intensity of light incident on a photo sensitive surface is doubled. Then

The nature of climax community is most dependent upon

How does the intensity of scattered light depend onthe wavelength of incident light ? State the condition when this dependence hold.

Electrode potential depends upon

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. If potential difference across the tube is increased then

In the photoelectric effect the velocity of the ejected electrons depends upon the nature of the target and

Nature of fruit developing from a flower depends upon the type of
