Visible light & radio waves Both are electromagnetic waves Then why only radio waves are able to pass the wall... !!!

what are electro magnetic rays

Although visible and radio waves are electromagnetic wave,but they highly differ in their wavelength/frequency... Thus radio wave being of higher wavelength is able to pass through the wall but visible doesn't..:-)

Right...Frequency is responsible for this problem But exactly what is the roll of frequency to make this difference.. How it is responsible...

frequency really related with the speed of a wave production as it is the number of waves per second
