Question

An eco is heard on a daywhen temperature is about 22degree Celsius will the Eco beheard sooner or later in thetemperature falls to 4 degreecelcius? justify the answer

Answer 1

As echo is directly proportional to distance and temperature, as temperature increases, the echo will be heard sooner as increase in temperature will allow more space for the sound particles to hit the destination and come back or return to the starting position.Similarly as temperature decreases, the space for the sound particles will be reduced than at normal and the echo will only be heard little later.
