Re: M.Sc Chemistry Entrance Question Papers
Here is the question paper of M.Sc Chemistry Entrance exam of IGNOU which you are looking for 1 The electromagnetic radiation associated with which of the following transitions in a hydrogen atom will have the maximum wavelength ? (1) From n =1 to n = 3 (2) From n = 2 to n = 3 (3) From n = 3 to n = 4 (4) From n =1 to n a 2 Potassium ejects photoelectrons when irradiated with light of wavelength less than 710 nm. Which of the following lights will eject photoelectrons from potassium with maximum velocity ? (1) Blue (2) Green (3) Violet (4) Yellow 3.
