Problem: A pipe open at one end only has a fundamental frequency of 228 Hz. A second pipe, initially identical to the first pipe, is shortened by cutting off a portion of the open end. Now, when both pipes vibrate at their fundamental frequencies, a beat frequency of 13 Hz is heard.
Part A: How many centimeters were cut off the end of the second pipe?
I need help to find how many centimeters were cut off the end of the second pipe and the speed of sound is 343 m/s.
