Water waves approaching the shore will slow down. Which statement describes another change that occurs?(1 point) Responses The frequency increases. The frequency increases. The wavelength increases. The wavelength increases. The wavelength decreases. The wavelength decreases. The frequency decreases.
As a wave travels from one medium to another, its wavelength triples. Which statement describes the speed and frequency in the new medium?(1 point) Responses The speed will stay the same, and the frequency will triple. The speed will stay the same, and the frequency will triple. The speed will triple, and the frequency will stay the same. The speed will triple, and the frequency will stay the same. The speed will stay the same, and the frequency will also stay the same. The speed will stay the same, and the frequency will also stay the same. The speed will triple, and the frequency will also triple.
The speed will stay the same, and the frequency will stay the same.
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 decrease by 5%. The wavelength would decrease by 5%. The wavelength would increase by 5%. The wavelength would increase 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.
The wavelength would decrease by 5%.
An earthquake sends seismic waves outward from the epicenter. The waves travel through different media in different directions. What will be true for all people who feel the earth shaking?(1 point) Responses The seismic waves will be equally far apart for all observers. The seismic waves will be equally far apart for all observers. The amplitude of the shaking will be the same for all observers. The amplitude of the shaking will be the same for all observers. The seismic waves will travel outward at the same speed in all directions. The seismic waves will travel outward at the same speed in all directions. The earth will rise and fall with the same frequency
The seismic waves will travel outward at the same speed in all directions.
