According to science, gamma rays have the shortest wavelengh and the highest penatrating power. What if we go beyond this wavelengh but reduce the penetrating power.
In medical institutions, the patients who require radiotherapy end up dead due to exposure of these waves. if the penatrating power is lowered there is low chances of death. Vibrating the cancerous cell more than its frequency can destroy them. A patient would only need to go to the radio sessions once in his/her lifetime.
usage of this kind of wave ,not only can it be used in medical institutions, but also in other places for example radio stations, fibre optic cables ; hence transmitting data faster than usual. this can also replace wireless networks such as bluetooth, which is slow and has a short range.
