Which is a correct way to measure wavelength?
a. from rarefaction to rarefaction for a longitudinal wave
b. from crest to trough for a transverse wave
c. from rest position to crest for a transverse wave
d. from compression to rarefaction for a longitudinal wave

the answer is a.) form rarefaction to rarefaction for a longitudinal wave because the particles in a wave is spread out i think all i know the answer is A so yeah

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
