Answer:
60.1 is the answer
Explanation:
Got it right on acellus and the test
The fundamental frequency it creates is calculated by the formula
Wavelength = speed of sound / frequency
F = v / λ
= 343 / 4.28
= 80.1 Hz
What is frequency ?
"Frequency is the number of occurrences of a repeating event per unit of time." It is also occasionally referred to as temporal frequency to emphasize the contrast to spatial frequency, and ordinary frequency to emphasize the contrast to angular frequency.
Other units: cycles per second (cps); revolutions.
SI unit: hertz (Hz)
In SI base units: s−1
Derivations from other quantities: f = 1 / T
