3. Determine the wavelength of a note made by an open pipe of length $0.246 \mathrm{~m}$. What note does this make?
\(\boxed{0.492}\) m is the wavelength of the note made by an open pipe of length 0.246 m
Step 1 :Given the length of the open pipe, L = 0.246 m
Step 2 :Using the formula for the wavelength of a note made by an open pipe, \(\lambda = 2L\)
Step 3 :Substitute the given length into the formula, \(\lambda = 2 \times 0.246\)
Step 4 :Calculate the wavelength, \(\lambda = 0.492\) m
Step 5 :\(\boxed{0.492}\) m is the wavelength of the note made by an open pipe of length 0.246 m
