when a beam of white light is passed through the vapours or a gas, the element absorbs certain wavelengths, while the rest of wavelengths are passed through it. The spectrum of this radiation is called atomic absorption spectrum.The missing wavelengths appear as dark lines in the spectrum.

Who developed an empirical equation from which the wave lenghts of lines in the spectrum of hydrogen atoms can be calculated?
Rydberg
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?

What part of the star is responsible for the dark lines in its spectrum?
Atoms in the atmosphere of the star is responsible for the dark lines in its spectrum.

What happens to the light that is missing in an absorption spectrum?
it is absorbed by atoms in the cool low density cloud and then remitted in all different directions as a continuous spectrum
The lines in the bright line spectrum of an atom are due to what?
The atomic line spectrum comes from the emission of atoms of different elements that are in an excited state. Each element has its own unique atomic emission spectrum.

Why is sun shine?
When its atoms fuse it releases a bunch of energy and radiation, some of which is in the visible spectrum of light.
The bright-line spectrum produced by the excited atoms of an element contains wavelengths that are?
in the visible light range
How many different protons of radiation were emitted from excited helium atoms to form the spectrum?
six photons
Which type of spectrum is produced by nebulae consisting of atoms that release photons when electrons jump from high-energy states to lower-energy states?
Emission spectrum is produced by nebulae consisting of atoms that release photons when electrons jump from high-energy states to lower-energy states.
Excited mercury atoms emit light strongly at a wave of 436 nm What is the frequency of radiation What is the energy of this radiation Good illustration of the electromagnetic spectrum?
Ultraviolet. Most of the spectrum is invisible to people.
