Question

If the temperature of seawater is 3°C and the frequency of sound waves is 16 kHz, the sound absorption is more likely to be less than 1.20 dB/km.

A) True
B) False

Answer 1

The absorption of sound in water varies with frequency and temperature; at 3°C and 16 kHz, absorption may be less than 1.20 dB/km depending on other influencing factors.

Step-by-step explanation:

The question is related to the absorption of sound waves in seawater at a specific temperature and frequency. In general, the absorption of sound in water increases with frequency and temperature. However, at a low temperature of 3°C and a higher frequency of 16 kHz, it is possible that the absorption could be less than typical values. Empirical models and experimental data would need to be referenced to provide a precise answer. Absorption is also influenced by factors such as water salinity, pressure, and the presence of dissolved gases or particulate matter.
