coz they hav very low frequency and long wavelength which helps them to penetrate most objects

Electromagnetic waves are electric and magnetic fields, and will pass through objects that can support these fields. This includes most insulators. Conductors cannot transmit electromagnetic waves, because electrical conductors cannot support electric fields. However, some materials may be conductive at low frequencies but insulative at higher frequencies, so they may block light, but let radio waves to pass. Some materials will absorb or interfere with the fields in the wave. Atoms can absorb electromagnetic radiation of certain frequencies, allowing certain frequencies can pass while others cannot.

All are waves of different lengths or frequencies. If you take a white light of a certain frequency and pull it longer or make it short you get x-rays, gamma ray, iR waves. Now there are spaces between particles like nucleus, electrons, etc. get a wave the be the right shape length and you can just go through the spaces..or if your off you can hit them.

actually that guy is wrong about wavelengths X rays have high energy very short wavelengths
gamma rays are even shorter
This allows them to be more concentrated and penetrate through objects
remember they are basically energy. Think how you can put a flashlight under your hand and your hand looks red. Thats because the light has enough room to pass around between atoms in your hand. Its like the same with radiation but intenser.

they have shorter wavelength, so can travel through small atoms
