EM Wave

Althought Light is an electromagnetic wave it can't be deflected by electric and magnetic fields. Why?

Because electric and magnetic fields don't exert forces on electromagnetic waves, they exert forces on charged particles.

Light is influenced by nearby charged particles and vice versa.

Light has no charge so electric and magnetic fields don't have an effect on it. It's no more complicated than that.

If that isn't "convincing" then please let us know why you are asking? Perhaps some context will let us know how to help you better.

Generally we say that light is an electromagnetic wave. Electric and magnetic fields are perpendicular to each other. Based on this consequence I am asking why the light is unaltered under electric and magnetic fields.
Plz do reply..

Please check post #3, where you'll see that I did respond.

However you are free to disregard my comment. Maybe someone else will be able to explain it in terms you can understand.

Here's a question for you... why do you think EM fields should be affected by EM fields?
