Modern Physics 1 Question 25
22. Imagine an atom made up of proton and a hypothetical 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 hypothetical particle to the first excited level. The longest wavelength photon that will be emitted has wavelength

(d)
Show Answer
Solution:
- In hydrogen atom,
Here, the electron has been replaced by a particle whose mass is double of an electron. Therefore, for this hypothetical atom energy in
The longest wavelength
This gives,
