Wave A has a lower frequency than Wave B.
Explanation:
Frequency is the number of waves passing through the unit time.
As the statement of the question says that the coils in wave A are widely and tightly spaced.
While in wave B the coils are widely and very tightly spaced which means the number of coils is more and the frequency of wave B is more than wave A.
Therefore more coils will pass through a fixed point in unite time and more will be the frequency.
Air resistance is the answer
