$4.$ A $256$ Hz tuning fork is vibrating over a long vertical tube partially filled with water. The first harmonic is heard when the water column in the tube is $0\mathrm{.}95$ m tall and the air column in the tube above the water is $0\mathrm{.}27$ m $.$

$($a$)$ How many wavelengths of sound are needed to produce the $1^{st}$ harmonic?

$($b$)$ What is the wavelength of the sound from the tuning fork?

$($c$)$ What is the speed of sound based on this experiment?

$($d$)$ At what height of the water column will the $2^{nd}$ harmonic be heard?
