Hydrogen has absorption lines at 656 nm and 486 nm. Where are the emission lines from hydrogen in this part of the electromagnetic spectrum?
A) 656 nm and 486 nm
B) 571 nm and 401 nm
C) 826 nm and 656 nm
D) 486 nm and 316 nm

Question

Quizplus · Accepted Answer

Emission lines occur at the same wavelengths as absorption lines for a given element, so hydrogen will have emission lines at 656 nm and 486 nm.
