Questions and Answers

What is the SI unit of frequency?

  • Meter
  • Hertz (correct)
  • Joule
  • Second

    • How is the time period of a sound wave defined?

  • Time taken for two rarefactions to cross a point
  • Time taken for a compression to cross a point
  • Time taken for two compressions to cross a point
  • Time taken for one complete oscillation (correct)

    • What is the relationship between frequency and time period of sound waves?

  • $v = 2T$
  • $v = \frac{1}{T}$ (correct)
  • $v = T^2$
  • $v = T$

    • Why do sounds of different pitch reach our ears even though they may travel at the same speed?
