How Is This Standing Wave Possible?

The video explores standing wave patterns on a string, focusing on the unexpected occurrence of a standing wave at 22 hertz, despite previous lessons indicating it was not possible. The instructor explains that this anomaly is due to the left end of the string not being a true node, allowing for non-integer multiples of half wavelengths. The video includes calculations of the wave's wavelength and speed, confirming the hypothesis. The lesson concludes with a discussion on different wave patterns in various instruments and a preview of future lessons.
