Question

Calculate the depth if a sound is set vertically downward the shift and echo from the sea bed is heard in 0.5seconds later,take velocity as 1500m/second square

Answer 1

T=0.5 s

S=1500 m/s

D = ?

Time = distance / speed

T/2 = d/s

(Since it is an echo it has travelled the same distance twice , so the time taken would be halved )

0.5/2 =D / 1500

D= 0.5/2× 1500

D = 1/4 × 1500

D = 375 m
