Research vessels at sea can create images of their surroundings
by sending out sound waves and measuring the time until they detect
echoes. The image of a shipwreck on the ocean bottom shown was made
from the surface with 600 kHz ultrasound.
What was the wavelength? Use values given in (Figure
2) if necessary.
Express your answer with the appropriate units.
How deep is the shipwreck if echoes were detected 0.57
s after the sound waves were emitted?
Express your answer with the appropriate units.
