If the light from Balmer series of hydrogen is used to eject photoelectrons from a metal, then the maximum work function of the metal can be
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
In the case of hydrogen like atom, the maximum energy liberated by the Balmer series is, n1=2, n2=∞ We know that energy is given by, ⇒E=13.61n12-1n22 eV ⇒E=13.6×14 eV ⇒E=3.4 eV Thus, 3.4 eV is the maximum work function of the…
