An air-filled pipe is found to have successive harmonics at 630 hz , 810 hz , and 990 hz . it is unknown whether harmonics below 630 hz and above 990 hz exist in the pipe. what is the length of the pipe? what type of pipe do you have?

0.95277 m

one end closed and the other end open

Explanation:

The harmonics are

630, 810, 990

So,

This can be only done when the pipe has one end open and the other end closed.

The fundamental frequency is 90 Hz

Fundamental frequency is given by

The length of the pipe is 0.95277 m

The pipe has one end closed and the other end open
