Question

The hydrogen atom in the ground state is excited by mass of monochromatic radiations of wavelength
` lambda Å ` . The resulting spectrum consists of maximum `15` different lines . What is the value of ` lambda` ? (`R_H = 109737 cm^(-1))`.
A. `937.3 overset(0)(A)`
B. `1025 overset(0)(A)`
C. `1236 overset(0)(A)`
D. `618 overset(0)(A)`

Answer 1

Correct Answer - A
Transition is `6 rarr 1, (1)/(lambda) = R_(H)z^(2) [(1)/(n_(1)^(2))-(1)/(n_(2)^(2))]`
