Which of the following spectral series in hydrogen atom give spectral line of 4860 Å
Text Solution
Verified by ExpertsThe correct answer is:
B
Step 1: Understand the spectral series of the hydrogen atom. The spectral series are defined as:
Step 2: Since 4860 Å is in the visible spectrum (specifically, it corresponds to blue-green light), we can conclude this line must belong to the Balmer series, which covers the visible region with wavelengths ranging approximately from 4000 Å to 7000 Å.
Therefore, the spectral line of 4860 Å corresponds to option B: Balmer.
- Lyman series: Transitions to n=1 (UV region)
- Balmer series: Transitions to n=2 (Visible region)
- Paschen series: Transitions to n=3 (IR region)
- Brackett series: Transitions to n=4 (IR region)
Step 2: Since 4860 Å is in the visible spectrum (specifically, it corresponds to blue-green light), we can conclude this line must belong to the Balmer series, which covers the visible region with wavelengths ranging approximately from 4000 Å to 7000 Å.
Therefore, the spectral line of 4860 Å corresponds to option B: Balmer.
