Speed of sound in silicon
WebThis means, the lateral speed of the wave peak is extremely high, something like 1700 km/h at equator, which is higher than speed of sound in air. It is known for supersonic objects to create... WebWhile not negligible, this is not a strong dependence. At 0 °C, the speed of sound is 331 m/s, whereas at 20.0 °C, it is 343 m/s, less than a 4 % increase. Figure 17.6 shows how a bat uses the speed of sound to sense distances. Figure 17.6 A bat uses sound echoes to find its way about and to catch prey.
