Stethoscope :Stethoscope is a medical diagnostic instrument based on multiple reflection of sound waves. This is used by doctors for listening to the sounds produced inside the body, particularly in the heart or lungs.
What are the application of multiple reflection of sound?
Uses of multiple reflections of sound are: Sound producing devices that uses a conical shape like megaphones to increase the intensity of sound waves in particular directions. Stethoscope: Sound undergoes multiple reflections in the wires of the stethoscope.

(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.

Sound is vital to sharing information, interacting with other people, creating art, regulating schedules, and countless other aspects of life.
Sound waves can assess potentially dangerous atherosclerotic plaques, monitor chronic liver disease, and help deliver drugs to particular locations within the body. Ultrasound devices can image tumors deep inside the body, and acoustical energy can be focused upon those tumors as a way of treating cancer.
What are the uses and importance of sound?
Sound is important because it engages audiences: it helps deliver information, it increases the production value, it evokes emotional responses, it emphasises what’s on the screen and is used to indicate mood.

Which of the following working on the concept of multiple reflection?
Kaleidoscope works on the concept of multiple reflections.
What is multiple reflection?
Multiple reflections are seismic events that have undergone more than one reflection between source and detector. As a seismic wave travels through the earth, it is split into a reflected and a transmitted wave at each acoustic discontinuity.
What is practical application in research?
Theoretical learning is what the knowledge is about and the practical application is how the knowledge learnt needs to be implemented in certain real life situations.
