For a sound wave,
Speed = Wavelength x Frequencyv = λ x ν
Speed of sound in air = 344 m/s (Given)
(i) For, ν= 20 Hz
λ1= v/ν = 344/20 = 17.2 m
(ii) For, ν= 20000 Hz
λ2= v/ν = 344/20000 = 0.172 m

Longest Wavelength of Sound in Air
The longest wavelength of sound that a boy can detect can be determined by finding the lowest frequency within his audible range and using the formula for wavelength.
Audible Range of the Boy
The given audible range of the boy is from 30 Hz to 16500 Hz. This means that the boy can hear sound waves with frequencies ranging from 30 cycles per second to 16500 cycles per second.
Determining the Longest Wavelength
To find the longest wavelength of sound that the boy can detect, we need to find the lowest frequency within his audible range. In this case, the lowest frequency is 30 Hz.
Using the Formula for Wavelength
The formula for wavelength is given by: wavelength = speed of sound / frequency
The speed of sound in air is approximately 343 meters per second.
Substituting the values into the formula, we have:
wavelength = 343 m/s / 30 Hz
Calculating the Longest Wavelength
wavelength = 11.43 meters
Therefore, the longest wavelength of sound that the boy can detect is approximately 11.43 meters.
Summary
- The audible range of the boy is from 30 Hz to 16500 Hz.
- The lowest frequency within his audible range is 30 Hz.
- The formula for wavelength is wavelength = speed of sound / frequency.
- The speed of sound in air is approximately 343 meters per second.
- Substituting the values into the formula, we find that the longest wavelength of sound that the boy can detect is approximately 11.43 meters.
The longest wavelength of sound that a boy can detect can be determined by finding the lowest frequency within his audible range and using the formula for wavelength.
