During the discharge of hydrogen gas, visible light is emitted. To which principal energy level must the electrons fall to produce these specific spectral lines?
Q1. During the discharge of hydrogen gas, visible light is emitted. To which principal energy level must the electrons fall to produce these specific spectral lines?
Answer: n=2
Explanation: The Balmer series results from transitions to n=2; Lyman series involves transitions to n=1, producing ultraviolet radiation.
