What is inside a photon?
In physics, a photon is a bundle of electromagnetic energy.
It is the basic unit that makes up all light.
The photon is sometimes referred to as a “quantum” of electromagnetic energy.
Photons are not thought to be made up of smaller particles..
Are photons immortal?
1 Answer. A photon is immortal if it does not meet some matter on its way, or even another photon. If it meets a particle, it will interact with some probability given by quantum mechanical calculations. In that sense it is not immortal, because in interacting it may be completely absorbed into new particles.
Can a photon lose energy?
A photon doesn’t lose energy unless it collides with a particle. Photons can scatter off interstellar electrons, for example. (Perhaps you were thinking about particles, like electrons, losing energy “in transit” in a vacuum. … Photons carry energy, but they don’t lose energy just because they travel.
Can a photon have mass?
Light is composed of photons, so we could ask if the photon has mass. The answer is then definitely “no”: the photon is a massless particle. According to theory it has energy and momentum but no mass, and this is confirmed by experiment to within strict limits.
Do photons attract each other?
Photons do not have mass or charge, which is why they have little to no effect on each other as they cross paths; they neither attract nor repel one another.
Why are there 7 colors in the rainbow?
Rainbows appear in seven colors because water droplets break white sunlight into the seven colors of the spectrum (red, orange, yellow, green, blue, indigo, violet). … You might be able to see a second rainbow above the main one in which the colors are in reverse order.
Which light travels faster red or blue?
Because the number of subquantum energy in a red photon is less than that of a blue photon, red photon interactions are less than the blue photon in the medium. So, the red light travels faster than the blue light.
Which is faster electron or photon?
A photon in a vacuum always travels faster, as it travels at the speed of light, which electrons, being massive particles, cannot achieve. In a medium, it is possible for electrons to travel faster than photons. For instance, in water, a high energy electron can travel faster than the speed of light in water.
Are there anti photons?
The short answer to “are there anti-photons” is “yes”, but the disappointment here is that anti-photons and photons are the same particles. … Particles that are their own antiparticles must be electrically neutral, because an aniparticle has the opposite electrical charge as its partner particle.
Can two photons annihilate?
The answer is yes, photons may collide and produce other particles. One familiar reaction is the low-energy annihilation of an electron and an anti-electron (known as a positron)– the result is usually a pair of photons (sometimes you get more than two). … This happens all the time in particle physics experiments.
What happens when two energies collide?
When two beams collide, all that energy packed into such a small vacuum of space explodes and creates mass in the form of subatomic particles (think of Einstein’s famous equation: energy equals mass multiplied by the speed of light squared).
What happens when two light rays collide?
Although light interacts with atoms, photons do not normally interact with other photons until you reach really high energies. For example, two gamma-ray photons can collide and produce an electron and a positron. But visible-light photons pass straight through each other, so they don’t interfere. … like a light wave.
How does a photon die?
A photon, conversely, “dies” when its electromagnetic energy is transformed into another form of energy. … So a photon can be transformed into other energy and, thus, “die” by any means we might use to convert energy from one form to another.
Do photons exist forever?
Now, by studying ancient light radiated shortly after the big bang, a physicist has calculated the minimum lifetime of photons, showing that they must live for at least one billion billion years, if not forever.
Which color photon travels the fastest?
redBecause the colors of light travel at different speeds, they get bent by different amounts and come out all spread out instead of mixed up. Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top.
Can two photons collide?
However, two photons heading towards each other can indeed collide indirectly. … For example, a photon can turn into an electron and an anti-electron. If two photons head towards each other and they both turn into electron/anti-electron pairs at about the same time, then these particles can interact.
What color travels fastest?
red lightViolet light has the shortest wavelength and is bent the most. Thus violet light travels more slowly through glass than does any other color and red light travels fastest.
