Does a photon have mass?
The photon does not have any known rest mass. This implies that it does not have to travel at the speed of light. This allows the photon to travel through a curved path without causing a time dilation effect on itself or anything it passes by. If a photon were traveling at the speed of light, it would have the same effect that a very fast moving particle would have on objects around it. This is why the speed of light is defined as the upper limit of the speed of all massless
Does a photon have rest mass?
A photon does not have rest mass. It does not experience any force in the vacuum of space. It can travel at the speed of light in all directions and it will travel in the same way in any medium. It will experience the same resistance to travel in a vacuum as it will in a pile of sand. The photon has no weight or inertia. As a result, a photon does not need a mass to move, because it moves all by itself. However, it acts like a wave,
Does photons have mass?
We know that photons are the particles of light, which move at the speed of light. At first glance, it does not seem possible that something with no mass could travel so fast. However, the special relativity theory tells us that the speed of light in vacuum is independent of the motion of the source. This can be seen in the equation E=mc2, where E is the energy, m is the mass of the particle, c is the speed of light in vacuum and is the famous
Does a photon have weight?
The short answer is no, a photon does not have weight or mass. As mentioned above, photons are elementary particles, which are the building blocks of matter. The fact that they are massless is not a coincidence. General relativity suggests that mass is a product of the force an object gives out. If an object has no mass, it is because it does not give off any force. This is because the force would be the same for the object from all directions. This is called the “
Does a photon really have rest mass?
Probably the most confusing question regarding the photon is whether it has rest mass at all. There’s no doubt it has energy. In fact, we know that it has energy because an object’s energy is directly proportional to its mass, and the photon has no mass. In particle physics, however, an object’s energy is also directly proportional to the square of its momentum. The photon’s energy is just equal to its momentum multiplied by the speed of light, so
