Question

write a letter to your friend telling him about your village activities​

Answer 1

Answer:

We are surrounded by a variety of sounds that generate from different sources. But, have you ever thought how sound waves travel? It is surprising how we can listen to cloud thunder which happens far away in the stratosphere. If we look closely, we can surely notice small activities that prove the existence of reflection of sound.

Take two tubes and place them alongside a wall. Now, put a speaker or some sound source close to one end of the tube. You will observe that sound can be heard at the other end of the tube. With the help of this activity, it is proven that surface of the wall does reflect the sound waves. Therefore, we will now try to learn in-depth about the reflection of sound waves and its applications.
