Question
Which points represent the compressions in the graphical wave representation shown?
- AEIM
- BFJ
- DHL
- CGK
Hint:
Compression or crest are created when the sound waves propagate.
The correct answer is: AEIM
- Compression or the crest is represented by A, E, I, and M.
- Rarefaction or the trough is represented by C, G, and K.
- Compression or crest determines the wavelength of the propagating wave
