Answer:3.185KHz

Explanation:

Where

Length (L) = 2.7cm

Speed (V) = 344m/s

Wavelength of the fundamental standing wave: λ = 4L

λ = 4L

Frequency is the rate per second of a vibration constituting a wave.

Frequency is given as:

F = v / λ

Therefore,

Frequency = v/4λ

Frequency = 1 * (344m/s) / 4 * (2.7cm)

Convert centimetre to meter

100cm = 1m

Convert Hz to kiloHz

1000Hz = 1kHz

Frequency = 3.185KHz
