Since the speed of sound is directly proportional to the frequency of the sound wave, and since wavelength is inversely proportional to frequency, the wavelength would also increase to match the new speed of sound. Therefore, the correct answer is:
The wavelength would increase by 5%.
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)
The wavelength would increase by 5%.
The wavelength would decrease by 5%.
The wavelength would stay the same.
The wavelength would change to match the new frequency.
