Select the correct answer.
an online wave simulator created these four waves. which wave has the lowest frequency?

Option B is having lowest frequency

Explanation:

Frequency of waves is defined as the number of cycles or number of waves per second.

So here as we can see the repetition or number of cycles is more then it is showing more frequency.

So here maximum frequency is for option c)

Similarly if the number of cycles or repetition is minimum then it will have least frequency in it.

So here minimum frequency in given all figures is for option B)

0.11 m/s and 0.28 m/s should be correct

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.
