The ejection of the photoelectron from the silver metal in the photoelectric effect experiment can be stopped by applying the voltage of 0.35 V when the radiation 256.7 nm is used. Calculate the work function for silver metal.
We know Energy of the incident radiation = Work function + KE of photoelectron
Work function = Energy of the incident
radiation - KE of photoelectron ..(1).Now energy of the incident radiation (E) = hv

Answer : A
Solution : (a) The value of n=3 and l=1 suggests that it is a 3p-orbital while the value f `m_(l)=0` [magnetic quantum number ] shows that the given 3p-orbital is `3p_(z)` in nature. <br> <img src="//d10lpgp6xz60nq.cloudfront.net/physics_images/ARH_31Y_NEET_CHM_C02_E01_007_S01.png" width="80%"> <br> Hence, the maximum number of orbitals identified by the given quantum number is only 1, i.e. `3p_(z)`.
What is the maximum number of orbitals that can be identified with the following quantum numbers?n=3,l=+1,ml =0
