WebA dog bark falls into the category known as mid frequency while a bird song (depending, of course, upon the bird) is often considered high frequency. Mid frequency is comprised of … Scientists have recently learned that elephants emit infrasonic waves of very low frequency to communicate over long distances to each other. Elephants typically migrate in large herds that may sometimes become separated from each other by distances of several miles. Researchers who have observed … See more When a wave reaches the boundary between one medium another medium, a portion of the wave undergoes reflection and a portion of the … See more Reflection of sound waves off of surfaces can lead to one of two phenomena - an echo or a reverberation. A reverberation often occurs in a … See more Diffraction involves a change in direction of waves as they pass through an opening or around a barrier in their path. The diffraction of water waves was discussed in Unit 10 of The Physics Classroom Tutorial. In that unit, … See more Reflection of sound waves off of surfaces is also affected by the shape of the surface. As mentioned of water waves in Unit 10, flat or plane surfaces reflect sound waves in such a way that the angle at which the wave … See more
Why do low frequency sound waves travel farther than high
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 ...
