Answer
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)
Responses
The wavelength would increase by 5%.
The wavelength would increase by 5%.
The wavelength would decrease by 5%.
The wavelength would decrease by 5%.
The wavelength would change to match the new frequency.
The wavelength would change to match the new frequency.
The wavelength would stay the same.
