Sonar systems used in water send out sound waves that reflect off the environment and then are detected. As water gets denser, the speed of sound in water increases. What would happen to the wavelength of a sonar wave as it moves into water with a 5% higher speed of sound?(1 point)

Question

Responses

The wavelength would increase by 5%.
The wavelength would increase by 5%.

The wavelength would stay the same.
The wavelength would stay the same.

The wavelength would decrease by 5%.
The wavelength would decrease by 5%.

The wavelength would change to match the new frequency.

Answer 1

The wavelength of a sound wave is related to its speed and frequency by the equation:

\[ \text{Wavelength} = \frac{\text{Speed}}{\text{Frequency}} \]

If the speed of sound in water increases by 5%, but the frequency remains constant, the wavelength will also increase by 5%.

Therefore, the correct response is:

The wavelength would increase by 5%.
