When the pitch of note produced by a harmonium is lowered, then the wavelength of the note :

(a) decreases

(b) first decreases and then increases

(c) increases

(d) remains the same

Solution

The pitch is a function of the frequency. That means the higher the pitch the higher the frequency and we all know the higher the frequency the shorter the wavelength. So decreasing the pitch increases the wavelength.
