This physics video tutorial explains the concept of sound waves and how shows you how to calculate the wavelength, frequency, and velocity of sound waves. It also shows you how to calculate sound intensity, intensity level in dB or decibels, beat frequency, and how to solve problems with open and closed organ pipes / tubes plus the doppler effect. This video contains the formulas and equations that you need for this chapter / topic as well as many examples and practice problems.
