What is the wavelength of sound waves in hydrogen gas corresponding to the lower limit of audibility ? If speed of sound in hydrogen gas is 1350m/s

Answer»

HII friend,


# ANSWER- 67.5 m


# EXPLAINATION-

# Given-

speed of SOUND in H2 gas = 1350m/s

we KNOW that lower limit of audibility frequency = 20Hz

(Audibility = 20Hz to 20000Hz)


# Solution-

For a sound wave,

Speed = frequency × wavelength

Wavelength = speed/frequency

Wavelength = 1350/20

Wavelength = 67.5m


- Wavelength of sound wave through hydrogen gas at lower limit of audibility is 67.5m.


Hope I was useful...
