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... |
