Harmonics are found when we can fit a whole (integer) wavelengths along the string or integer +0.5 wavelengths. If the string is 7.6 cm long. What would be wavelength of the smallest standing wave we could fit on the string? (Hint: we can have a harmonic at 0.5 of a wavelength)

We call this standing wave the Fundamental. Immersive Reader
