_____ wavelength sound usually produces higher quality images with greater detail.

• A. Longer
• B. Narrower
• C. Shorter
• D. Lower

Answer: (C)

Shorter wavelength sound usually produces higher quality images with greater detail because resolution improves as wavelength gets smaller. When the wavelength is shorter, the waves can interact with finer features and the imaging system can distinguish two close structures as separate, producing sharper borders and more detailed internal features. This is tied to higher frequency; as frequency increases and wavelength decreases, axial resolution improves. The trade-off is that higher-frequency (shorter-wavelength) sound attenuates more quickly, so penetration depth is reduced, which is why shorter wavelengths are best for shallow imaging but not ideal for deep structures.
