Answer:
2Hz
Explanation:
Find the diagram attached
Using the formula;
v = fλ
v is the velocity
f is the frequency
λ is the wavelength
Given the following
v = 3.2m/s
λ = 4.8/3 = 1.6m
Get the frequency
f = v/λ
f = 3.2/1.6
f = 2Hertz
Hence the frequency of the wave is 2Hz
The measurements used in the experiment is the amount of speed over time.
The measurement of speed is indicated along the “y” axis.
Upon viewing the graph, the highest point along the “y” axis shown is 25 m/s. This would be the maximum.
The maximum speed of the car would be 25 m/s.
As we know that the pitch of sound is directly proportional to the frequency as the frequency increases the pitch of sound increases and wavelength decreases
so the correct option is B
