Concept explainers
Sound from Source A has a frequency twice as great as the frequency of sound from Source B. Compare the wavelengths of sound from the two sources.
To compare: The wavelength of sound from two sources
Answer to Problem 42A
Sound from source A has half the wavelength as that of sound from source B.
Explanation of Solution
Given:
The frequency of source A sound is twice the frequency of sound from source B.
Formula used:
The relation between frequency, speed and wavelength is,
Here,f is frequency and λ is wavelength.
Calculation:
As
So,
Conclusion:
Therefore, sound from source A has half the wavelength as that of sound from source B
