Dark lines especially in solar spectrum have been named as Fraunhofer lines. These line are good examples for line absorption spectrum
No. Atomic emission spectrum is non-contiuous and it is named as line spectrum.
Band spectrum is the spectrum given by the molecules. It consists of series of closely spaced lines known as bands separated by the dark spaces.
Dark lines in an absorption spectrum are caused by material existing between the source of light and the observation point. This material can absorb light from the source at specific energies corresponding to the excitation energies of the molecules, atoms, or ions making up the material.
It's a line spectrum because of the quantization of energy- meaning you only see energy with levels n=1,2,3.... One would never see the energy level n=2.8 for instance- that would be the case if it were continuous rather than a line spectrum.
Lippershey first discovered a dark-line spectrum.

The dark lines reveal the atoms that are associated with the stars atmosphere. The dark lines are atom energy absorption signatures.

Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.
The dark lines represents the absorption of energy at that frequency, E=hf.

There are several kinds of spectra. Bright line spectrum, or emission spectrum, is when light emitted by a gas has an electrical discharge going through it, and it produces a spectrum of just a few isolated parallel lines.
