A sound wave in a steel rail has a frequency of 620 Hz and a a wavelength of 10.5 m. What is the speed of sound in steel? Show your work.
The speed of sound in any medium can be calculated using the formula:
v = f × λ
where v is the speed of sound, f is the frequency, and λ is the wavelength.
Substituting the given values, we get:
v = 620 Hz × 10.5 m
v = 6510 m/s
Therefore, the speed of sound in steel is approximately 6510 m/s.
To find the speed of sound in steel, we can use the formula:
Speed = Frequency x Wavelength
Given:
Frequency (f) = 620 Hz
Wavelength (λ) = 10.5 m
Substituting the values into the formula:
Speed = 620 Hz x 10.5 m
Speed = 6510 m/s
Therefore, the speed of sound in steel is 6510 m/s.
