Question

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 1

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...

Answer 2

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 67.5
