Why do photons travel so fast?

Some people say that the reason a photon travels at light speed the moment it is created is because it is a massless particle, and therefore must always travel at the speed of light. All quantum objects are partly waves and therefore can have a speed the moment they are created.

What if the speed of light was faster?

If the speed of light was, say, 100 km/h, we could experience the effects of special relativity in our day to day lives. Cars passing by would appear as pictures on a sheet of paper. Their headlights would be dark blue, perhaps even brightly violet, while their tail red lamps would be invisible.

Why do photons travel in waves?

In energy wave theory, a photon is generated by the vibration of particles, traveling perpendicular to the direction of vibration. These are the two components of the wave (longitudinal and transverse). Longitudinal waves constantly flow from particles, causing an electric field even when a particle is not in motion.

Can photons travel slower than the speed of light?

A team of Scottish scientists has made light travel slower than the speed of light. They sent photons – individual particles of light – through a special mask. It changed the photons’ shape – and slowed them to less than light speed.

Why does light move at all?

Light is a manifestation of the laws of electromagnetism, which show that whenever sources of electric charge – such as electrons – are accelerated, the resulting energy is converted into waves of electromagnetic energy that travel outward from the source at the speed of light.

What do photons move in?

It is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force. Photons are massless, so they always move at the speed of light in vacuum, 299792458 m/s (or about 186,282 mi/s).
