ANSWER
625 m/s
EXPLANATION
Given:
• The frequency of the sound wave, f = 250 Hz
,• The wavelength, λ = 2.5 m
Find:
• The speed of the wave, v
The speed of a wave of wavelength λ and frequency f is given by,
[tex]v=f\cdot\lambda[/tex]Substitute the known values and solve,
[tex]v=250Hz\cdot2.5m=625m/s[/tex]Hence, the speed of the wave is 625 m/s.
