As the intensity of incident light increases

If intensity of incident light is increased in photo electric effect then which of the following is true ?

What is the effect on the maximum kinetic energy and the numver of photoelectrons when (i) The intensity of incident light decreases. (ii) The emitting surcac is charged. (iii) Wavelength of incident light increase.

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 explains the PE, where upsilon= frequency of incident light and phi= work function. Q. The slope of the graph between stopping potential and frequency is [here h is the Planck's constant and e is the charge of an electron] is

Assertion : Photoelectric current depends on the intensity of incident light. Reason : Number of photoelectrons emitted per second is directly proportional to intensity of incident radiation.

Light from sodium lamp is made to pass through two polaroids placed one after the other in the path of light. Taking the intensity of the incident light as 100% , the intensity of the out coming light that can be varied in the range

The angle between polariser and analyser is 30^(@) . The ratio of intensity of incident light and transmitted by the analyser is

STATEMENT-1: The kinetic energy of photo-electrons increases with increase in frequency of incident light were vgtv_(o). STATEMENT-2: Whenever intenksity of light is increased the number of photo-electron ejected always increases.

In a photoelectric effect experiment, the graph of stopping potential V versus reciprocal of wavelength obtained is shown in the figure. As the intensity of incident radiation is increased :
