What is meant by the atomic spectra?

What is meant by the atomic spectra? Correct Answer Series of colored lines with dark spaces in between

When atoms are excited, they emit light of certain wavelengths which corresponds to different colors. The emitted light can be observed as a series of colored lines with dark spaces in between them, this series of colored lines is called atomic spectra.
