give any two examples of sound reflection
Answers
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.
Answer:
(a) Reflection of sound is used to measure the distance and speed of underwater objects. This method is known as SONAR. (b) Working of a stethoscope is also based on reflection of sound. In a stethoscope, the sound of the patient's heartbeat reaches the doctor's ear by multiple reflections of sound.
