Discuss graphical variation photoelectric current with potential difference in photoelectric cell and explain what information do you get from this graph?

What is photoelectric cell? Explain any one of the photoelectric cell.

The sum and difference of two vectors are equal in magnitude. What conclusion do you draw from this?

Sketch a graphs showing the variation of stopping potential with frequency of incident radiations for two photosensitive materials A and B having threshold frequencies v_0>v_0' respectively? What information do you get from the slope of the graphs?

Draw a graph showing the variation of stopping potential with frequency of incident raditions in relation to photoelectric effect. Deduce an expression for the slope of this graph using Einstein's photoelectric equation.

On increasing the current drawn from a cell, the potential difference across its terminals is lowered why?

An electric circuit consisting of a 1 m long metallic wire XY, an ammeter, a voltmeter, 4 cells of 1.5 V and a plug key was set up. Draw a schematic diagram of this electric circuit on the on positon. Following grpah was plotted between the values of potential difference and current. what conclusins do you draw about the relation between V and I from this graph? state this relations in your words.

In an experiment on photoelectric effect, the following graphs were obtained between the photoelectric current 'I' and anode potential V. Name the characterstics of this incident radiation that was kept constant in this experiment.

Sketch a graph between frequency of incident radiations and stopping potential for a given photosensitive material. What information can be obtained from the value of the intercept of potential axis? A source of light of frequency of greater than the threshold freuency is placed at a distance of 1 m from the cathode of a photocell? the distnace of hte light sources from the cathode is reduced explain giving reasons, what change will you observe in the Stopping potential.
