What else can I help you with?
What have we found that travels closest to the speed of light?
Particles such as neutrinos and photons have been observed traveling very close to the speed of light. Neutrinos are known to have tiny but non-zero mass, while photons are massless particles that always travel at the speed of light in a vacuum.
What will happen if you increase the mass in light?
Photons ('particles' of light) have zero rest mass. When they move at the speed of light (the normal situation) they do have momentum due to the relativistic nature of the Universe. If we were to hypothesize light particles with mass the development of the Universe would be entirely different.
What types of radiation particles have no weight?
Gamma rays are the only ones. Alpha particles are helium nuclei, and Beta particles are electrons or positrons, all of these have mass.
Why is the speed of electron beam greater than the light speed in cathode ray oscilloscope?
It isn't. Nothing travels faster than light, especially an electron. If it tried it would become infinitely heavy as it reached the speed of light. You would then need an infinite force to accelerate it further. To know more, Google on "special relativity"
Heat waves traveling at the speed of light are called?
Heat waves traveling at the speed of light are called RADIATION! :)
Which are the non relativistic particles?
A non-relativistic particle is any particle not traveling at a speed close to the speed of light. This is not a property of particular type of particle; any particle may in general travel at any speed (below the speed of light). An exception are particles which are massless such as photons and gluons, these MUST travel at the speed of light.
What have we found that travels closest to the speed of light?
Particles such as neutrinos and photons have been observed traveling very close to the speed of light. Neutrinos are known to have tiny but non-zero mass, while photons are massless particles that always travel at the speed of light in a vacuum.
What is a particle without mass and what are its properties?
A particle without mass is called a massless particle. Massless particles travel at the speed of light and do not experience gravitational forces. They have energy and momentum, but no rest mass. Examples of massless particles include photons (particles of light) and gluons (particles that mediate the strong nuclear force).
Why traveling at the speed of light would we disperse?
No such thing would happen. Matter cannot reach the speed of light, only massless things can (and they cannot travel at any other speed than the speed of light).
What is the significance of momentum for a massless particle?
The significance of momentum for a massless particle is that it determines the particle's energy and direction of motion. Since a massless particle always travels at the speed of light, its momentum is directly proportional to its energy. Momentum is crucial for understanding how massless particles, such as photons, interact with other particles and fields in physics.
Why can nothing be closer than light to the relativity barrier?
Actually there are things that travel at the speed of light other than light itself. According to special relativity all massless particles must travel at the speed of light, so this includes for example gluons, or the particles that supposedly mediate gravity, the gravitons (the 'speed of gravity' is equal to the speed of light). The prime reason why this must be so is that the speed of light must be the same for all inertial observers according to special relativity and if massless particles could travel at slower speeds than you can have an observer for which such a massless particle would not be moving, but because it has no mass it would have no energy at all; it would not exist! Massive particles must always travel slower than the speed of light because the energy required to accelerate any particle with mass to the speed of light is infinite. A more technical answer is that all particles must be in a representation of the Lorentz group and a massless representation only exists if the speed is that of light all the time. Likewise massive representations cannot exist at the speed of light.
Why light don't travel at an infinite speed?
Because at infinite speed, it's mass will become zero, which is not possible as it consists of photons which are not massless particles.
Is that true that the more energy of a photon the bigger the mass it possesses?
No, all photons have the same mass. Photons are massless (i.e. zero). All the energy in a photon is in its momentum, but increasing its momentum does not change it speed which is always "the speed of light". All massless particles always move at the speed of light.
Does light have mass?
No, light does not have mass. It is composed of particles called photons, which are massless and travel at the speed of light in a vacuum.
How does photon differ from inertial particle?
A photon is said to be "massless", meaning that it has no REST MASS (of course, having energy, it also has an equivalent mass).In a vacuum, a photon can ONLY move at the so-called speed of light (about 300,000 km/second). "Regular" particles can ONLY move at sub-light speed. They can get close to the speed of light, but never quite reach it.
Does light create its own mass?
Light does not have mass. Remember, as an object's speed approaches the speed of light, its mass approaches infinity, therefore it will require infinite energy to accelerate something to the speed of light, therefore only massless particles can travel at light speed.
is there anything lighter than photon?
No, photons are considered to be massless and travel at the speed of light, making them the lightest known particles.
