Waves in Different Media Quick Check

Question

1.) Which measure does not change when a wave moves from one medium to another?
-frequency-

2.) Water waves approaching the shore will slow down. Which statement describes another change that occurs?
-The wavelength decreases-

3.) As a wave travels from one medium to another, its wavelength triples. Which statement describes the speed and frequency in the new medium?
-The speed will triple, and the frequency will stay the same-

4.) 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?
-The wavelength would increase by 5%-

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?
-The earth will rise and fall with the same frequency-
