The emission spectra of atoms in the gaseous phase do not show a continuous spread of wavelength from red to violet, rather they emit light only at specific wavelengths with dark spaces between them. Such spectra is/are called

The emission spectra of atoms in the gaseous phase do not show a continuous speed of wavelength from red to violet, rather they emit light only at specific wavelength with dark spaces between them. Such spectra are called line spectra or atomic spectra or discontinuous spectra.
