Question

In a test to measure the depth of the

sea bed, ultrasound wave pulses took
0.40s to travel from the surface to the
sea bed and back. Given that the
speed of sound in sea water is
1350m/s, calculate the depth of the
sea bed below the surface.

Answer 1

270 m

Step-by-step explanation:

d = depth

waves must travel down and back up = 2 d

2d = .40 s * 1350 m/s

2d = 540 m

d=270m
