Question

The velocity of ultrasonic sound in water is 1400 m. If the time taken by the SONAR to receive the reflected wave is 15 s then what will be the depth of the ocean detected by it?​

Answer 1

Answer

Given :-

• Velocity (v) of ultrasound = 1400m/s
• Time (t) taken to reflect wave

To find :-

• Depth (d) of ocean.

Solution :-

By using Formula

$2d = vt$

$d = \frac{1400 \times 15}{2} \\ d = 700 \times 15 \\ d = 10500m$

The depth of ocean is 10500m
