(a) Draw a graph showing variation of photo-electric current (I) with anode potential (V) for different intensities of incident radiation. Name the characteristic of the incident radiation that is kept constant in this experiment.
(b) If the potential difference used to accelerate electrons is doubled, by what factor does the de-Broglie wavelength associated with the electrons change?
(a) The frequency of incident radiation was kept constant.
(b) de-Broglie wavelength,
If potential difference V is doubled, the de-Broglie wavelength is decreased to 1/√2 times.
