A closed organ pipe has a length of 2.40 m?

[TheCuriosity]

A closed organ pipe has a length of 2.40 m.

a.) What is the frequency of the note played by the pipe? Use
343 m/s as the speed of sound.

b.) When a second pipe is played at the same time, a 1.40 Hz beat note is heard.
By how much is the second pipe too long?

The a.) problem's solution is 35.7 Hz. and b.) problem's solution is 0.10 m

The actual problem here is that I don't know how to properly solve b.)

I'm lost... I'm new here.I just don't know here to post my question lol. I wasn't trying to solve this problem. Can you guys help me and tell me how to solve both of a.) and b.)and tell me where can I post this question if this was the wrong section.Thanks in advanced :)

I just read Mentor's message. I'm sorry for messing up xDI understand that you guys won't do my homework, but could you PLEASE help me and explain how to solve b.) ?

This is the correct section.So as the Mentor said,
- What are the relevant equations for this problem?
- What have you done to try to solve the problem?

Only then will we be able to help you.Sorry
If that was a question given to you,you must be knowing some relevant equations or some method to solve it.
