What is the speed of the wave.
It was learned earlier in Lesson 4 that the slope of the line on a velocity versus time graph is equal to the acceleration of the object. Sound travels at a speed of 343 metres per second in air or 1484 metres per second in water Humans can normally hear sounds between 20Hz and 20000Hz 20kHz. The speed of sound through air. The speed of a longitudinal wave through a liquid or gas depends on the density of the fluid and the bulk modulus of the fluid Here the bulk modulus is defined as V.
