Question
A sound source sends waves of 400 Hz. It produces waves of wavelength 2.5 m. The velocity of sound waves isSelect an answerA100 m/sB1000 m/sC10000 m/sDNone of these
Solution
The velocity of a wave can be calculated using the formula:
Velocity = Frequency x Wavelength
Given in the problem, the frequency (f) is 400 Hz and the wavelength (λ) is 2.5 m.
Substituting these values into the formula, we get:
Velocity = 400 Hz x 2.5 m = 1000 m/s
So, the correct answer is B1000 m/s.
