Question
The lowest resonant frequency for a spring is 0.750 flz. If the length of the spring is 5.60 m, what is thespeed of the wave in the spring?a. 4.20 m/s c. 6.00 m/sb. 5.60 m/s d. 8.40 m/s
Solution
The speed of a wave can be calculated using the formula:
v = f * λ
where: v is the speed of the wave, f is the frequency, and λ is the wavelength.
In this case, we know the frequency (f) is 0.750 Hz. We also know that the length of the spring is 5.60 m, which is the wavelength (λ) of the wave.
Substituting these values into the formula gives:
v = 0.750 Hz * 5.60 m = 4.20 m/s
So, the speed of the wave in the spring is 4.20 m/s. The correct answer is (a) 4.20 m/s.
