To compare:
The vibration on the string compare to the vibration in the air?
Answer to Problem 1OQ
Solution:
The vibration on the string and the vibration in the air have the same frequency.:
Explanation of Solution
When pianist plays the note “middle C,” the speed of the wave in the string is define as
Here,
is the length of the string
is the frequency
As the sound wave from string travel to the air, the sound wave changes it medium, due to the change in medium the speed and wavelength of the wave differs due to different properties of the medium but the frequency of the sound wave remains the same.
Hence the vibration on the string and the vibration in the air have the same frequency.:
