Which one of the following is the unit of frequency of a sound wave?a)...
  • As we know that frequency(f) =  = s-1 or min-1 or hertz
  • So, from the given options the unit of frequency of sound wave is s-1
  • Frequency, is the number of waves that pass a fixed point in unit time.
  • Also, the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
  • So if the time it takes for a wave to pass is 1/3 second, the frequency is 3 per second. If it takes 1/50 of an hour, the frequency is 50 per hour.
Note-
  • Decibel(dB) is the unit of intensity of sound.
