are there atoms in light?

Light is not made out of atoms or anything like them. Electromagnetic waves are themselves a basic ingredient of our world. It's the light itself which enters our eyes. It is absorbed by special molecules which change their chemical configuration as a result of that absorbed energy.

In chemistry and physics, an atom is the smallest particle of a chemical element that retains its chemical properties. An atom consists of a dense nucleus of positively-charged protons and electrically-neutral neutrons, surrounded by a much larger electron cloud consisting of negatively-charged electrons.

Neither one. Light is EM radiation, like radio waves. “Analog” and “digital” refer to two means of encoding information onto such signals, and light can be used to carry either form.

Atoms, electrons, protons and neutrons do behave like particles. But that's not the whole story. Atoms, electrons, protons, and neutrons also behave like waves! In other words, matter is just like light in that it has both wave-like and particle-like properties.

Atoms represent the smallest pieces of matter with constant properties, and are referred to as the basic unit of matter. However, scientists have discovered that atoms are not the smallest particles in nature. Despite their minuscule size, a number of much smaller particles exist, known as subatomic particles.

Protons are about the size & mass of electrons which are the smallest (by far) of the 3 elements of an atom. So no, photons don't contain atoms, photons are smaller than atoms. Photons are fundamental particles. That means they're not made of anything else.

Light is the result of electrons moving between defined energy levels in an atom, called shells. When something excites an atom, such as a collision with another atom or a chemical electron, an electron may absorb the energy, boosting it up to a higher-level shell.

Atomic Particles Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electron shells and contain the electrons (negatively charged).

Atoms consist of a nucleus made of protons and neutrons orbited by electrons. Atoms are the basic units of matter and the defining structure of elements. ... We now know that atoms are made up of three particles: protons, neutrons and electrons — which are composed of even smaller particles, such as quarks.

Light is composed of particles called photons, and matter is composed of particles called electrons, protons, neutrons. It's only when the mass of a particle gets small enough that its wavelike properties show up. To help understand all this let's look at how light behaves as a wave and as a particle.

How do atoms emit light? Light is the result of electrons moving between defined energy levels in an atom, called shells. When something excites an atom, such as a collision with another atom or a chemical electron, an electron may absorb the energy, boosting it up to a higher-level shell.

Light as electromagnetic waves Light consists of electromagnetic waves. Electromagnetic waves are a combination of vibrating electric and magnetic fields which travel through space at a very high speed. If the rate of vibration of these fields is millions of times per second, we can detect them as radio waves.

Both radio waves and light are electromagnetic waves; their main difference is their frequency. Radio waves are created by the acceleration of electrons in a radio antenna, and light waves are created by the oscillations of the electrons within atoms.

Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. ... Most of an atom is empty space.

Yes, all things are made of atoms, and all atoms are made of the same three basic particles - protons, neutrons, and electrons. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. ... They are the glue that holds atoms together in chemical bonds.

The shadow, technically, is not a tangible thing. It is an illusion created by the absence of light in contrast to the surrounding area which is now illuminated by the torch. So, technically, the shadow is not made of atoms, but the area where the shadow occurs is.
