Is light a ray or a wave or a particle, how light travels in the highest speed

 Q1) Light a ray or a wave or a particle

Ans- In first of classes light is taught to us as a ray and it travels in a straight line 

But then after in further classes its told light is a wave 

Then again in higher classes it is told light is a particle

Now we will get confused that is light a ray or a wave or a particle 

Light is a particle called photon, 

It is also a electromagnetic wave, a transverse wave

Q2) How light travels in higest speed?

Ans- Light is made of a particle called photon. Photon is a massless particle, that means it has no mass, now we know that if a particle has no mass then there will be no resistance force (i.e. Friction, gravity) nothing will stop this Photon, so that's the reason light travels very fast.
