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.
