Animal migration monitoring – a greatly utilized method in wildlife biology, conservation biology, and wildlife administration through which modest battery-powered radio transmitters are attached to wild animals so their movements might be tracked with a directional RDF receiver. Sometimes the transmitter is implanted while in the animal. The VHF band is typically utilised considering that antennas Within this band are rather compact.
When oil or gas is spilled, colourful styles are formed by skinny-movie interference. Since the Huygens–Fresnel theory states that each stage of a wavefront is connected with the manufacture of a fresh disturbance, it is achievable for a wavefront to interfere with itself constructively or destructively at diverse destinations producing brilliant and darkish fringes in common and predictable styles.
A Stockbridge damper Simply because power lines can have problems with aeroelastic flutter pushed by wind, Stockbridge dampers tend to be connected into the lines to reduce the vibrations.
Radio communication. basics Details such original site as sound is converted by a transducer like a microphone to an electrical signal, which modulates a radio wave produced by the transmitter.
