    Question

    One end of a slinky lying on a table is fixed to a rigid support. The free end of the slinky is pushed back and forth. As a result, alternate compressions and rarefactions are observed. The former and the latter refer to the loops of the slinky to be ____ and ____ respectively.

    1. Farther apart, farther apart
    2. Closer together, closer together
    3. Closer together, farther apart
    4. Farther apart, closer together

    Hint:

    Compression and rarefaction are produce when the sound wave propagates through a medium

    The correct answer is: Closer together, farther apart

      • Compression is the region where the particles are close together.
      • Rarefaction is the region where the particles are farther apart.
      • So, the correct option is c.
