Question

what makes a light photon to travel so that speed​

Answer 1

Answer:

Explanation:

Light photons have mass which is equal to 0.

So they can travel at lightspeed.

Answer 2

Answer:Light is made up of photons that travel at a speed of 300,000 km per second in the vacuum of space. Light is a product of the Sun converting hydrogen into helium.  Visible light is merely energy that you can see.  Under the photon theory of light, a photon is a discrete bundle (or quantum) of electromagnetic (or light) energy. Photons are always in motion and, in a vacuum, have a constant speed of light to all observers, at the vacuum speed of light (more commonly just called the speed of light) of c = 2.998 x 108 m/s.  It is the energy that each photon has that allows it to travel at the speed of light.  Photons are also mass less.Basic Properties of Photons

According to the photon theory of light, photons . . .  

move at a constant velocity, c = 2.9979 x 108 m/s (i.e. "the speed of light"), in free space  

have zero mass and rest energy.
