WebLow Frequency (LF) RFID. LF RFID systems operate at 125 kHz and 134 kHz. This frequency band provides a short read range of 10 to 50 cm, and has slower read speed than the higher frequencies, but is not very sensitive to radio wave interference. High-Frequency (HF) RFID. Most HF RFID systems operate at 13.56 MHz with read ranges between 10 cm ... WebDiffraction is a process bending light ray due to present of obstacle in its way and wavelength of incoming ray affects the amount of diffraction. Whenever waves strike a hole or an apex in an obstacle, they pass through the hole or beyond the obstacle’s corner.

WebIn general though, the penetration of an EM wave is determined by the absorption of whatever you're trying to penetrate. The very high frequency (high energy gamma rays) … WebLower frequency waves travel further as surface waves. They tend to follow the earth's curvature due diffraction and attenuation. Diffraction causes bending and is inversely proportional to the wave's frequency. Attenuation, along with energy loss, also makes the waveform to tilt downwards. This essentially helps in following the earth's curvature.
