  • This Physics video tutorial explains the concept of standing waves on a string. It shows you how to calculate the fundamental frequency and any additional harmonics or overtones. In addition, it shows you how to identify and count the number of nodes and antinodes on a standing wave given the number of loops. This video contains plenty of examples and physics practice problems.

    14:46 The fundamental frequency of a certain standing wave is 175 Hz. Calculate the first 4 harmonics.
    16:12 The 7th Harmonic of a standing wave is 280 Hz. What is the frequency of the 4th and 9th Harmonic?
    17:35 A 2 meter string produces a standing wave with 3 loops.
    a) What is the standing wavelength?
    18:56 b) What is the frequency if the speed of the wave is 45 m/s?
    20:00 c) What is the wavelength and speed of the first harmonic?
    22:37 The wavelength of a standing wave with one loop is 12 meters. Find the wavelength of the first five harmonics.

    You are literally the reason why I am falling in love with physics. Never have I ever found physics so much easier to follow than whenever you explain it. As someone who lowkey has the attention span of a goldfish, I sit through some of your longer (2+ hours) videos and still thoroughly enjoy it.

    from the other force end. A transverse wave is set up at the lower end. Show that the
    velocity of the wave increases up along the rope. Give the expression for the time taken
    for the wave to reach the fixed end.
