Answer» Data : n = 510 Hz, v = 340 m/s, v = n = = This, the wavelength, is the distance covered by the SOUND wave in ONE vibration of the string.When the string completes 250 vibrations,the distance covered by the sound waves 250 250 x = 166.7 m⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ORThe distance covered by sound during 510 vibrations of the string is 340 m. HENCE, the distance covered by sound during 250 vibrations of the string 250 x 166.7 m |
