V d t where v is the velocity d is the distance and t is the time so you can read it as Speed Distance Time. In this video Josh Kenney explains how to use the wave equation to find wavelength speed and frequency of a waveThanks for watchingSupport The Science C. We get Newtons formula for the speed of sound in airHence On substituting the values of atmospheric pressure and density of air at STP in equation relationwe find that the speed of sound waves in air comes out to be 280 ms -1whereas its experimental value is 332ms -1.
Find the distance that an object has traveled.
Using the formula above calculate the wave speed. For general purposes the equation speed distancetime or s dt is usually the easiest way to calculate speed. The speed of a sound wave refers to how fast a sound wave is passed from particle to particle through a medium. A transverse wave travelling at the same speed with an amplitude of 5 cm has a frequency of 15 Hz.
