In this video we will cover:-
1.A photon of wavelength 4 × 10–7 m strikes on metal surface, the work function of the metal being 2.13 eV. Calculate (i) the energy of the photon (eV),(ii) the kinetic energy of the emission, and (iii) the velocity of the photoelectron (1 eV= 1.6020 × 10–19 J).
2.What is the maximum number of emission lines when excited electron of a H atom in n=6 drops to the ground state?
3.Calculate the wavelength for the longest wavelength transition in the Balmer series of atomic hydrogen?
4.A golf ball has a mass 40g and a speed of 45m/s.If the speed can be measured within accuracy of 2%, calculate the uncertainty in the position?
5.The mass of an electron is 9.1 x 10-31kg. If its K.E. is 3.0 x 10-25 Calculate its wavelength?
6.What is the total number of orbitals associated with the principal quantum number n=3?
