Most Goanetters should know this. But in case someone does not, let me state the obvious. Reliable medical knowledge cannot be sought from the random claims made by lay journalists in newspapers and political activist websites screaming all kinds of world-wide conspiracies. As I have mentioned

I am happy to scientifically educate Ferdinando and correct his mistakes even though he keeps trying to insult me for some reason. Most cell phones and cell phone towers emit radio waves just outside the range of what are regarded as microwaves. Microwaves is just a term generally used for

Ultrasonic waves are sound waves greater than 20 kHz in frequency. In other words, they are propagating pressure oscillations, or alternating compressions and rarefactions, occurring at a periodicity of more than 20,000 times per second in a medium such as air or water. Bats produce and sense

Another perfect example on Goanet of exposing one’s ignorance. RF Radiation has frequencies between 3 kHz to 300 GHz, and it is used in radio communications, as well as communication devices. Microwave radiation is a type of non-communication RF Radiation, and is a subset of the RF frequencies.

Santosh: Please note that bats produce and sense ultrasonic sound waves, not radio frequency electromagnetic waves. Please let me know if anyone likes to know the difference between the two. Me: I want to know.But please do not post links. Write in a nut shell,in broad lines of comparison
