A string vibrates in 4 segments to a frequency of 400 Hz.
(a) What is its fundamental frequency?
(b) What frequency will cause it to vibrate into 7 segments?

Text Solution

Verified by Experts

The correct Answer is:
A, B
(a) `f_4 = 4f_0`
`:. f_0 = f_4/4 = 400/4 = 100 Hz`
(b) ` f_7 = 7f_0 = 700 Hz` .
