1.	When sound is reflected from a distant object, an echo is produced. Let the distance between the reflecting surface and the source of sound remain the same. Do you hear an echo sound on a hotter day? Justify your answer.
Answer» Solution :n echo can only be heard if it reaches the ear after 0.1 secs. TIME TAKEN `=("Total DISTANCE")/("Velocity")` As on a hotter day, the velocity of sound is more. So if the time taken by the echo is less than 0.1 sec than it WONT be heard.
