Deduce an expression for velocity of em waves in vacuum

Please find below a detailed version giving the answer to your question

LIGHT IS TRANSVERSE

In transverse wave,the particles vibrate perpendicular to the direction of wave propagation.

“light is a transverse wave.”
but light can be propagated without a medium , that is particles.
so, how can light be called as a transverse wave?

Answer:

Light is an electromagnetic wave which requires no medium for the propagation. In electromagnetic waves including light, electric and magnetic fields vary with time in mutually perpendicular directions and also perpendicular to the direction of propagation.

A Question from Electromagnetic Waves

Rajat asked: –

we know that electric and magnetic field are associated with charged particle but when light travells,it produces electric and magnetic field both but it consests of photons,which is a uncharged particle.why it did so?

Master will soon answer this.

Electromagnetic Waves :: Doubts continue …

Siva Sai asked:

why are oscillating electric and magnetic feilds created when an elctromagnetic wave is travelling?

Ans:

[wiki]Electromagnetic waves[/wiki] are produced by mutually perpendicular time varying electric and magnetic field mutually reinforcing each other.
