A

-
B

a wavelength
A transverse wave does not have a compression.
In transverse waves, particle displacement is perpendicular to the direction of wave propagation, so there are no regions of high particle density (compressions) or low density (rarefactions), features exclusive to longitudinal waves.
A) a compression
This is correct. Compressions occur only in longitudinal waves (e.g., sound), where particles oscillate parallel to wave motion. Transverse waves (e.g., light, rope waves) exhibit crests and troughs, not compressions.
B) an amplitude
Transverse waves do have amplitude, the maximum displacement from equilibrium. This is a fundamental property of all waves.
C) a frequency
All periodic waves, including transverse waves, have frequency, the number of oscillations per second.
D) a wavelength
Transverse waves have wavelength, the distance between consecutive crests or troughs. This is a standard wave characteristic.
Conclusion
Compressions are absent in transverse waves. The correct answer is A) a compression.
