electromagnetic radiation..

[Raju gurung]

I was just wondering if any one could explain me why is the sunlight called the electromagnetic wave. if quantum theory could explain i did not fine any of the site. my friend suggested me this sitehttp://www.physics-physicsdiscussion.blogspot.com Is it informative, i could not judge

well, all light is electromagnetic waves. everything from radio waves to gamma rays. its all electromagnetism just of various frequencies.

thanks for the reply but i wanted to know why is the lights called electromagnetic radiation:-)

Because it is electromagnetic waves radiated by some object?

Maxwell's equations of electromagnetism allow for waves in the electromagnetic field. These waves are interpreted as light.

 

Search for Maxwell's equations on google and I am sure you will find out more.

why is a ford focus called a car?

 

light is a subset of the larger group defined by electromagnetic radiation. just like a ford focus is a subset of the larger group defined by 'car'

Don't mind with this question but why is it that light does not need any medium to travel. And as you said ford focus is a subset of the larger group defined by ' car '. i think every process has a reson. That's what i am trying to grasp.

That was the big question 100+ years ago. It turns out that electric and magnetic fields do not rquire a medium, and that they can induce each other when they change in time. The result is an electromagnetic wave, which requires no medium.
