Answer 1

Uses are:-Stethoscope is used to hear the sound of internal organs of a patient for diagnostic purposes.
It is used In SONAR AND RADAR for detecting objects or estimating the position at sea in case of SONAR.

Answer 2

1) In big theaters,the walls behind the speaker are made spherical and the speaker stands at the focus of that ,so that sound is reflected towards the audience and the audience can hear it clearly.
2)In a megaphone,the principle of reflection of sound is used,the shape of megaphone is such that the sound after reflection goes in the forward direction.
3)The principle of reflection of sound is used in SONAR(sound navigation and ranging). In this technique, impulses of sound are transmitted towards the sea floor and the reflected impulse is recorded.The time for this is measured and the depth of the sea is calculated.
4)Reflection of sound also has applications in the ultrasound technology,which is used to detect the presence of any foreign object in the body or in the detection of any defects in the development of the foetus.
5)Bats cannot see in the dark.So, they use the reflection of sound to find their path and to avoid any obstacles in their path. They emit sound which we can't hear and when the sound reflects,they come to know about the obstacles in their path.

These are the applications of reflection of sound.

I hope You Understood it.
