gama zrak

gama zrak

Gamma rays are like the light we see with our eyes, the x-rays used to probe our bodies in search of problems, and the radio waves that our television sets translate into inane shows. The only difference among these types of electromagnetic radiation is the wavelengths of the waves and how fast they vibrate. Gamma rays are the most energetic (and vibrate the most); radio waves are the least energetic and vibrate the least.
