Based on the description provided:
- Wave A has a certain distance between its crests, which we refer to as the wavelength (lambda).
- Wave B has a similar amplitude above and below the horizontal line as wave A, but the distance between its crests is much shorter.
Since wave B has a shorter distance between its crests compared to wave A, it has a shorter wavelength. According to the wave frequency-wavelength relationship, a shorter wavelength corresponds to a greater frequency.
Thus, compared to wave A, wave B has a shorter wavelength and greater frequency.
The correct response is:
shorter wavelength and greater frequency.
