Question
Which points represent the rarefactions in the graphical wave representation shown?
- AEIM
- BFJ
- DHL
- CGK
Hint:
The points CGK in the given graphical representation represents the points of rarefaction.
The correct answer is: CGK
- The sound waves produce upper and lower pressure points on oscillation.
- Rarefaction is the peak produced downwards that has less pressure.
- The points CGK represents the points of rarefaction.
