The equation for wave speed can be used to calculate the speed of a wave when both wavelength and wave frequency are known. Finally calculate the wave speed. Sound in air 340 ms.
How to Calculate Wavelength.
Wave Speed Example First determine the frequency. To see how the speed of a wave on a string depends on the tension and the linear density consider a pulse sent down a taut string When the taut string is at rest at the equilibrium position the tension in the string latex F_T latex is constant. Therefore the speed of the wave is 350000000 ms. What is the speed of an electromagnetic wave whose length is 35m and has a frequency of 100000000 Hz.
