Question

Sound travels at 1500 m/s in water. How deep is an ocean if the echo from a transmitter takes 4 s to reach the receiver?

Answer 1

Answer:

$v = wavelength \times \: frequency$

Explanation:

given, v=1500m/s

t= 4s

freq.= 0.25

wavelength = velocity/time= 1500/4 = 375,

wave travels twice of distance then answer is

375 ×2

Answer 2

Answer:

Plz mark me brainliest

Explanation: It is an echo question so:-

Data:

-> Speed of sound= 1500 m/s

->Time=4s

Equation=

Distance=speed x time/2

= 1500x4/2

=6000/2

=3000m
