What is the name for the particles quanta of energy packets that are in visible light. These particles act as if they have mass but actually don't.?

Yes named as photon. It has momentum though it does not have mass
Its momentum is given by the expression p = h / l
Here h = Planck's constant and l - lambda the wavelength of radiation

Energy of visible light can be measured in organized packets called?
The energy of visible light can be measured in organized packets called photons. These photons have discrete values of energy, meaning there is exact amounts of energy these have, and don't vary in decimal places.
Does particles in the medium do not actually travel with the wave?
They don't. The energy of the wave is transmitted from one particle (or group of particles) to another. The energy of the wave moves along, the individual particles return to their resting position.
Can kinetic energy be visible?
The movement cause by the kinetic energy is visible.
Which has less kinetic energy warmer particles or cooler particles?
Cooler particles have less kinetic energy.
Why is there no such thing as sucking?
Because the "sucking" is actually pushing. For example. When there is an area of low pressure, air appears to get sucked into it, but actually it is being pushed by the air behind it. This is because air particles are in motion, and therefore posses energy. Some have more and some have less energy, but there is always a net. Most of this energy is kinetic energy, and the amount of particles dictate how many collisions there are between particles, and in the collisions particles move until they hit another particle. So, if there are less particles in the low pressure area to collide with, particles end up staying there longer than in the higher pressure area until equilibrium is reached. So, in effect the air particles are pushing other air particles to an area where they aren't being pushed.
What is a packet of light energy that carries a quantum of energy?
These packets of energy are called photons, which are exactly that - little packets of energy! Sometimes they behave as particles, and other times they tend to act like waves. Visible light often comes from atoms that are excited to a higher energy state, then drop back down.
Does the packets of energy mean particles having energy?
Yes, it's basically the same thing. Light energy (for example) comes in quanta, or "packets", that can't be further subdivided. The quanta are identified with particles, known as "photons".
Energy of visible light can be measured in organized packets called?
The energy of visible light can be measured in organized packets called photons. These photons have discrete values of energy, meaning there is exact amounts of energy these have, and don't vary in decimal places.
How are light and heat different?
Heat is the movement of particles. When a substance (let's use air in this example) "heats up", the individual particles are actually gaining kinetic energy. That's why there is a direct correlation between heat and pressure. Light, on the other hand, is made up of "packets" of energy called photons.
Is energy made of the same particles as matter?
Energy has absolutely no volume or mass. However, energy and matter can be interchanged, and highly energetic particles behave as if they have more mass. When antimatter and matter collide, they annihilate, releasing their equivalent in energy. The "particles" of which energy can be said to be composed are "photons" which are discreet, massless packets of energy. The so-called "solar wind" is not energy, but consists of high-energy particles emitted by the Sun along with its radiated energy.
How does the sun actually product energy?
hydrogen particles mix with helium particles
Why can you you model the thermal energy of an object as the 'mechanical energy' of the particles that make it up?
The heat becomes visible through electromagnetic energy
What is the energy pathway for an fluorescent source?
Electrical energy- Energy is then absorbed by mercury particles-ultra violet energy-energy absorbed by phosphor particles-visible light energy. This is what I found in my science textbook hopefully it helps.Thumbs up if it did.
How is the light made?
light is created by fast moving particles creating a form of visible heat energy
What is thermal light and electrical energy is at the microscopic level?
Not quite sure what you mean with "thermal light".* Light, and other electromagnetic waves, come in small "packets", or particles, called "photons" in this case. * Electrical energy is carried by charged particles, for example electrons, holes, or ions.
Is photon a particle or energy?
Photons are packets of energy
Does particles in the medium do not actually travel with the wave?
They don't. The energy of the wave is transmitted from one particle (or group of particles) to another. The energy of the wave moves along, the individual particles return to their resting position.
