Figure show the variation of the stopping potential `(V_(0))` with the frequency `(v)` of the incident radiations for two different photosensitive matererial `M_(1)` and `M_(2)` What are the values of work functions for `M_(1)` and `M_(2)` respectively

If the frequency of the incident radiation is equal to the threshold frequency, what will be the value of the stopping potential?Group of answer choices100 V0Infinite200 V

The electron in the hydrogen atom jumps from excited state (n=3) to its ground state (n=1) and the photons thus emitted irradiate a photosensitive material. If the work function of the material is 5.1eV, the stopping potential is estimated to be

Two light sources are used in a photoelectric experiment to determine the work function for a particular metal surface.When green light from a mercury lamp (𝜆 = 546.1 nm) is used, a stopping potential of 0.8 V reduces the photocurrent to zero.Based on this measurement, what is the work function for this metal?  Express your answer in units of eV.Answer for part 1What stopping potential would be observed when using light from a red lamp with wavelength 𝜆 = 647 nm?

A container consists of a sample of hydrogen like ions all of which are in the same state. In this state, ionization energy of an ion is 36 of ionization energy of hydrogen atom. This sample is now allowed to reach its most stable configuration, thereby resulting in 10 distinct types of photons. The most energetic Paschen-line photons from this sample are made incident on a metal. The stopping potential of the ejected photoelectrons is observed to be  3.704 V. Find the work function of the target (in eV) to the nearest integer.

Figure shows the plot of the stopping potentialversus the frequency of the light used in anexperiment on photoelectric effect. The ratio h/e is:
