Question

When a sound is reflected from a distant object, a echo is produced. Let the distance between the reflecting surface and the source of sound production remains the same. Do you hear echo sound on a hotter day

Answer 1

Heya....❤❤❤

here is ur answer...

An 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.

Hope it helps....

plzz mark me as brainliest my dear !!!

Answer 2

No. because hotter day the sound returned to the source earlier than 0.1s.
speed of sound directly proportion to temp.
