This is a fascinating question ! It makes you stop and try to
figure out what "ordinary" light might be.
ALL light is emitted by atoms.
That statement might possibly need some refinement for the case
where light and a bunch of other stuff comes pouring out of the core
of a star, or from the fireball of a nuclear weapon. But any light that
you and I have ever seen in the course of our daily lives has been
emitted by atoms.

∙ 12y agoThe question is stunning! Where do you imagine all the light you see
every day comes from ? It's all emitted from atoms.
We know how to produce radio waves by running current through wires,
up a cable, and out of an antenna, directly creating E & M fields that ripple
and wiggle out over vast distances. But no waves any shorter than those.
All the other electromagnetic radiation around us is the result of subatomic
particles ... mostly electrons ... hopping, skipping, jumping, and spinning
between the various energy levels in their respective atoms.
I'd be curious to know what you imagine to be 'ordinary' sources of light.

The atoms that make up a star can be determined by?
Spectroscopic analysis of the light emitted by the star.
Energy of the red light emitted by a neon atoms with a wavelength of 703.2 nm?
jl
Is UV light emitted from all lasers?
No, most lasers emit light at a different frequency than UV.
Why light emitted by bulb is not monochromatic?
Light bulbs aim to emulate the light emitted by the Sun, which radiates as a black body at 6000 degrees C. The light is emitted over the entire visible spectrum. Some bulbs produce monochromatic light, sodium street lights for example.
Do element atoms have their own color?
Element atoms do not have their own color. The color we see is a result of how light interacts with the atoms and their electrons. When light hits an atom, some of the light is absorbed and some is reflected. The color we perceive is the color of light that is reflected off the atoms. Different atoms can absorb and reflect different colors of light, resulting in the variety of colors we observe in the world.
One indicator that electrons in atoms are limited to specific energy levels is that?
light emitted from excited atoms occurs only at specific wavelengths
What different forms of emitted light are there?
fluorescence

Why two independent sources cannot behave as a coherent sources?
Light is emitted due to the de-excitaton of electrons from higher orbits of the various atoms of the light source.The de-excitation can also be to different levels in different atoms resulting in emission of different wavelengths.A light source will have numerous atoms in it.When you take two light sources it is not possible for all the atoms to get de-excited to the same shell at the same time(causing phase difference) that is why two independent sources cannot be coherent.
What was The quantum theory of energy levels within atoms was aided by?
The quantum theory of energy levels within atoms was aided by the emission spectrum. When excited with light, different elements emitted photons of different frequencies. The frequencies were different because the energy difference from excited to low energy state was different depending on the element.
What happens to the energy of a vibrating electron that does not collide with neighboring atoms?
The energy of a vibrating electron that does not collide with neighboring atoms has energy that is emitted as light. The energy will be radiated away.
How is ultraviolet light different from ordinary light?
It is not visible by the naked eye.
How is light water light different than heavy water?
Heavy water is heavier than light water because instead of both hydrogen atoms in the molecule being ordinary light hydrogen (H - one proton) one or both hydrogen atoms are heavy hydrogen (D - one proton, one neutron).
How lasers and ordinary light different?
a laser is just a focused beam of light
Is UV light emitted from all lasers?
No, most lasers emit light at a different frequency than UV.
