A beam of momechromatic light of wavelength `lambda` ejectes photonelectrons from a cesium `(phi = 1.9eV)` these photonelectron from a radius are made to ceslum with hydrogen atoms in ground state find the maximum value of `lambda` for which (a) hydrogen atoms may be ionised (b) hydrogen may get excited from the ground state to the first excited state and (c ) the excited hydrogen atoms may emit visible light
