The balmer series for the H-atom can be ob-served

Text Solution

Verified by Experts

The correct Answer is:

B, D

Balmer series for hydrogen atom can be observed by measuring the frequencies of light emitted due to transitions between excited states and the first excited state (n=2). In these measurements, we would find the sequence of frequencies will higher frequencies getting closely packed. Choices (a) and (d) are correct.
