Explanation
From the given graph it is clear that if we extend the given graph for A and B, intercept of line A on V axis will be smaller as compared to line B means work function of A is smaller than that of B.
In X-ray spectra, depending on the accelerating voltage and the target element, we may find sharp peaks super imposed on continuous spectrum. These are at different wavelengths for different elements. They form characteristic X-ray spectrum.
In photocell, at a particular negative potential (stopping potential V0) of anode, photoelectric current is zero, as the potential difference between cathode and anode increases current through the circuit increases hut after some rime constant current (saturation current) flows through the circuit even if potential difference still increases.
Stopping potential does not depend upon intensity of incident light (I).
Stopping potential is that negative potential for which photo electric current is zero.
Work function is the intercept on K.E. axis i.e. 2 eV.
All the positive ions of same specific charge moving with different velocity lie on the same parabola.
Stopping potential equals to maximum kinetic energy. Since stopping potential is varying linearly with the frequency. There, fore max. KE for both the metals also vary linearly with frequency.
On increasing wavelength of light the photoelectric current decreases and at a certain wavelength (cut off) above which photoelectric current stops.
Stopping potential is same for a and h, for hence their frequencies arc same. Also maximum current values are different for a and b so they will have different intensities.
