10) This question asks us to find the wavelength of a wave produced at the fundamental frequency of an organ pipe. We are also told that the organ pipe is open at both ends. Let's derive a general equation for this organ pipe.

Where is n is the harmonic number, L is the length of the organ pipe, and λ is the wavelength

The question asks us to find the wavelength at the fundamental frequency, which basically means at the first harmonic(n = 1).

Where is n is the harmonic number, L is the length of the organ pipe, and λ is the wavelength

Answer: C
