Why are humans not able to see,feel or hear radio waves? We are sensitive to the rest of the waves in the EM spectrum. If EM waves are composed of oscillating magnetic and electric fields, why am I not electrocuted by the electric constituent of the Radio waves?

In terms of human evolution, sensitivity to radio waves (like a radio wave “eye”) doesn’t buy us much. They are much longer in wavelength than visible light, which means they can’t tell us about as many small details of the environment as light waves can. They have other benefits – going through solid structures for example, or very long ranges – but it turns out that for most animals, what’s in front of them is much more meaningful than whether there is a mountain on the other side of the forest or not.
As far as electrocution, they’re very low power. If you got up close to a high power antenna, you’d get burned.
