In photoelectric experiment energy of $$2.48 \mathrm{~eV}$$ irradiates a photo sensitive material. The stopping potential was measured to be $$0.5 \mathrm{~V}$$. Work function of the photo sensitive material is :

Which of the following statement is not true about stopping potential $$(\mathrm{V}_0)$$ ?

Given below are two statements :

Statement I : Figure shows the variation of stopping potential with frequency $$(v)$$ for the two photosensitive materials $$M_1$$ and $$M_2$$. The slope gives value of $$\frac{h}{e}$$, where $$h$$ is Planck's constant, e is the charge of electron.

Statement II : $$\mathrm{M}_2$$ will emit photoelectrons of greater kinetic energy for the incident radiation having same frequency.

In the light of the above statements, choose the most appropriate answer from the options given below.

Given below are two statements: one is labelled as Assertion $$\mathbf{A}$$ and the other is labelled as Reason R.

Assertion A: Number of photons increases with increase in frequency of light.

Reason R: Maximum kinetic energy of emitted electrons increases with the frequency of incident radiation.

In the light of the above statements, choose the most appropriate answer from the options given below:
