Question
In the options given below, if ‘C’ means compression and ‘R’ means rarefaction figure out which of the patterns represent the pattern of particles of the medium through which sound propagates.
- CCRRCC...
- CRCRCR...
- CRCCRCCCR...
- CCRCR...
Hint:
Alternate compression and rarefaction are created by sound waves
The correct answer is: CRCRCR...
- A sound wave has an alternating pattern of compressions and rarefactions.
- Therefore, the pattern of particles of the medium through which sound propagates will be CRCRCRC...
- So, the correct option is b.
