Imagine an atom made up of a proton and a bypothetical particle of double the mass of the electron but having the same charge as the electron . Apply the Bohr atom model and consider all possible transitions of this bypothrtical particle that will be emited level . The longest wavwlength photon that will be emidet has longest wavwlength `lambda` (given in terms of the bytherg constant `R` for the hydrogen aton) equal toA. `9(5R)`B. `36//(5R)`C. `18//(5R)`D. `4//(5R)` |

Answer» Correct Answer - C KEY CONCEPT : `lambda prop (1)/(m)` For ordinary hydrogen atom, wavwlength `(1)/(lambda) = R [(1)/(2^(2)) - (1)/(2^(2))] = (5 R)/(36) ` or `lambda(36)/(5R)` with hypothencal particle , required wavwlength `lambda^(1) = (1)/(2) xx (36)/(5R) = (18)/(5R)` |
