Understanding the Science Behind Light: Exploring Its Properties and Behavior

[aby001234]

If light is an electromagnetic wave then y does it not travel any opaque object becoz all electromagnetic waves like radio waves pass thru all materials?
y is light not affected by magnetic field?
Can cohesive and adhesive forces be used to generate energy?
If yes then why and if no then why?
from where does cohesive or adhesive energy come from?
Plz help...

What makes you think that all electromagnetic waves pass through all materials?

y is light not affected by magnetic field?

Why should it be?

I don't know about you, but ultraviolet does not pass through my body, it gives me sunburn. Don't try passing microwaves through your body, they will cook you if they are strong enough (because they DON'T go through, they excite various molecules). The list goes on and on.

Light doesn't have a charge does it? So it won't be affected by a magnetic field. There are different types of light, they have different frequencies so some types won't travel through some things whereas some will.Can you try tidying your grammar, I had a bit of trouble reading what you said.

You are forgetting a SECOND player in this scenario - the nature of the material! What dictates how light propagate through a material isn't just a function of light, but also how that material behaves. If the material has some energy range where light in this energy is absorbed, then that light doesn't get transmitted.
