The type of spectra produced by atoms is:

Explanation

Atoms produce line spectra. This is because atoms emit light at only specific wavelengths, producing a line spectrum rather than the continuous spectrum of all wavelengths produced by a hot object. Bohr's model suggests that the atomic spectra of atoms are produced by electrons gaining energy from some source, jumping up to a higher energy level, then immediately dropping back to a lower energy level and emitting the energy difference between the two energy levels. This results in emission at specific wavelengths, or lines, hence the term "line spectra".
