Explanation

To find the wavelength of the first overtone (second harmonic) in a closed pipe, you can use the following formula:

Wavelength (λ) = 2 * L / n

Where:
- λ is the wavelength.
- L is the length of the closed pipe.
- n is the harmonic number.

In this case, you're looking for the first overtone (second harmonic), so n = 2, and the length of the closed pipe is given as 33 cm.

Wavelength (λ) = 2 * 33 cm / 2
Wavelength (λ) = 33 cm

So, the wavelength of the first overtone of a note in a closed pipe with a length of 33 cm is 33 cm.
