Suddenly this question came to mind. I was thinking, since both are waves, both have frequency and wavelength, But why can’t we see sound waves and hear to light rays?!! 😛 😀

Later i came to know reasonably good the answer for second one. No We can’t hear light waves. Sound waves are the waves which propagate through the medium through vibrations. Where as Electromagnetic waves doesn’t make any particle to vibrate or shake…! And Hence We Can’t.
