Question

Which describes the visible emission spectrum of hydrogen?
A. A series of lines converging at longer wavelength.
B. A series of regularly spaced lines.
C. A series of lines converging at lower energy.
D. A series of lines converging at higher frequency.

Answer 1

A series of lines converging at a higher frequency best describes the visible emission spectrum of hydrogen.

What is the emission spectrum of hydrogen?

• In the emission spectrum of hydrogen, there are only four lines that are visible.
• This is because the human eye can see things existing only in the visible region.
• The range of wavelengths of visible light is between 400 - 700 nm.
• The spectrum of Hydrogen in this region is known as the Balmer series having a value of 109,677 cm-1.
• Moreover, due to the short wavelength of the lines in the electromagnetic series, it has high frequency and high energy.
• So, the correct option is D
