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.
- Farther apart, farther apart
- Closer together, closer together
- Closer together, farther apart
- 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.
