Question

a ship send on a high frequency sound wave and receive an echo after 1 sec. what is the depth of sea . speed of sound in water=1500m/s

Answer 1

we know that distance = speed × time
but in echo the distance is two times
so..2distance = speed × time
2 distance = 1500 × 1
distance = 1500/2
distance = 750 metres
Hence the depth of the sea is 750 m

Answer 2

Answer:

the depth of sea is 750 m
