Question

why thunder contains several
echo
​

Answer 1

Answer:

we know,

s=vt

or, t=s/v

here, the velocity of thunder bolt is almost equal to the velocity of sound that is 332 m/s.

but the distance is very large from the clouds to the ground. so, u can hear an echo

the sound that we hear, strikes at different buildings having different heights. so we can hear echo several times.
