Deep underwater, a sub moves through still water at a speed of 23 m/s. The sub sends out a 910 Hz sonar wave towards an underwater mountain. The wave reflects off the mountain and the sub detects the reflected wave. (The speed of sound in water is 1482 m/s.) Hint: this problem requires two parts. The sub is the source for the initial wave. The frequency does not change when the wave reflects from the mountain. For the reflected wave, the sub is the detector. What frequency does the sub detect for the reflected wave?

Concept explainers

Electromagnetic Waves

Electromagnetic waves are waves that consist of magnetic field and electric field components perpendicular to each other. These field components are also perpendicular to the direction of propagation of the wave.

Question

Deep underwater, a sub moves through still water at a speed of
23 m/s. The sub sends out a 910 Hz sonar wave towards an
underwater mountain. The wave reflects off the mountain and
the sub detects the reflected wave. (The speed of sound in
water is 1482 m/s.) Hint: this problem requires two parts. The
sub is the source for the initial wave. The frequency does not
change when the wave reflects from the mountain. For the
reflected wave, the sub is the detector.
What frequency does the sub detect for the reflected wave?

A fisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. It takes 2.6 s for the boat to travel from its highest point to its lowest, a total distance of 0.53 m. The fisherman sees that the wave crests are spaced 4.8 m apart. How fast are the waves traveling? (Give your answer in m/s.)
