light is electromagnetic wave justify
Answers
Explanation:
Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light.
Explanation:
Why is light called an electromagnetic wave and why it is called by this name?
There is an established relationship between electric and magnetic fields.
Now,a changing electric field creates a changing magnetic field and that changing magnetic field creates another changing electric field and the process repeats itself and the wave can propagate even in vacuum.
Such a wave is called an electromagnetic wave.
The calculated theoretical value of the speed of an electromagnetic wave is very(very) close to the measured speed of light and hence light was called as an electromagnetic wave
