Since the speed of a wave on a string is inversely proportional to the square root of the linear mass density, the speed would be higher in the low linear mass density of the string. Shown below are three waves that were sent down a string at different times. The tension in the string remains constant

The linear mass density decreases. If L remains fixed, then the combined effects of increased tension and decreased linear mass density results in the wave velocity increasing, which, for a given driving frequency, means a longer resulting wavelength.
