Answer:
The wavelength of the sound waves are, λ = 26.92 m
Explanation:
Given data,
The frequency of the sound waves, f = 13 Hz
The speed of sound waves in air, v = 350 m/s
The velocity of the wave in the medium is equal to the product of its wavelength and its frequency.
The formula for the wavelength of the waves is,
λ = v / f
Substituting the given values in the above equations,
λ = 350 m/s / 13 Hz
= 26.92 m
Hence, the wavelength of the sound waves are, λ = 26.92 m
These values when compared seem to be the same. They are equal. If we convert them to the same units, they results to the value which is:
51.5 Hectograms = 5100 Grams
51,500 Decigrams = 5100 Grams
Hope this answers the question. Have a nice day.
