Answer:
The answer to the question is
Changing travel medium from one of low density to another of higher density (heavier weight) reduces the speed of the transmitted pulse
Explanation:
The rate of propagation of a wave in a medium is correlated to the properties of the medium. in a guitar, sound is produced by vibrating the string. The frequency of the produced sound depends on the speed and wavelength of the wave as follows
v = f × λ
The guitar strings, though having equal length, the produce sounds of different frequencies and they also have different linear mass density.
As highlighted, the speed of sound is a function function of the frequency and the frequency produced in a string is related to the linear density
The relation between speed with linear density of a material, or its mass per unit length is
v absolute = where
v absolute = The absolute velocity
= The horizontal tension on the string
= Mass per unit length of the string =
where
m = Mass of the string and
l = Length of the measured mass of string
There fore the wave propagates more slowly, or slows down when it changes its travel medium from one of lower linear mass density to a different medium having a higher density
The speed of the transmitted pulse reduces in the heavier string
