In this question, we are given that the C5 key in a piano has a frequency that is double of that of the C key. Our task is determine whether the string associated with the C5 key is shorter or longer than that of the C string.
The frequency f of a string is inversely proportional to the length l of the string.
Since the frequency of the C5 key is twice of that of the C key, then the C5 string must be shorter than the C string.
Result:
Shorter.
