Web802.11 WLANs use radio waves having frequencies of 2.4 GHz and 5 GHz, which means that the signal includes 2,400,000,000 cycles per second and 5,000,000,000 cycles per second, respectively. Signals operating at these frequencies are too high for humans to hear and too low for humans to see. WebThe electromagnetic spectrum includes X-rays. As the wavelengths of light decrease, they increase in energy. X-rays have smaller wavelengths and therefore higher energy. We usually talk about X-rays in terms of their energy rather than wavelength. This is partially because X-rays have very small wavelengths!
