Question

An open-ended pipe is 6 meters long. What is the wavelength of a first harmonic standing wave?

Answer 1

`"12 m"`

Explanation:

![https://notes.tyrocity.com/open-organ-pipe/]()

For an open pipe of length `"L"` first harmonic is formed when

`"L" = "λ"/2`

So, wavelength of first harmonic for a `6\ "m"` long pipe is

`λ = "2L"`

`color(white)(λ) = "2 × 6 m"`

`color(white)(λ) = "12 m"`
