Question

In a sonar, ultrasonic waves are sent into the sea water and the reflected waves from a sunken ship are received after 2.0 s. If the velocity of waves in sea water is 1450 $m/s$, find the depth of the sunken ship.

• A. 2900 m
• B. 1450 m
• C. 2800
• D. 3000

Answer 1

The correct option is B

1450 m

Given, $v$ = 1450 $m/s$ , $t=2.0s$

Depth of sunken ship $d$ = $\frac{Vt}{2}$

$d$ = $1450\times \frac{2}{2}$

$d=1450m$
