Wave Speed and Medium Characteristics

The video tutorial explains wave speed, emphasizing that it depends solely on the medium through which the wave travels, not on amplitude, frequency, or wavelength. Various experiments, including those with wave machines, slinkies, and ripple tanks, demonstrate how changes in medium characteristics like tension and density affect wave speed. The tutorial concludes with a detailed explanation of wave speed equations, showing how wavelength and frequency relate to wave speed.

Which of the following does NOT affect wave speed?
