Question

When light transmitted through the absorbing material after getting dispersed forms dark lines on a continuous bright background. This kind of spectrum formed is known as

• A. Line spectrum
• B. Band spectrum
• C. Line absorption spectrum
• D. Band absorption spectrum

Answer 1

The correct option is C Line absorption spectrum

After passing through an absorbing substance, some wavelengths of light are absorbed by the material so after dispersion takes place, some of dark lines are present on the spectrum due to missing wavelengths. This spectrum is called the line absorption spectrum.
