Which of the following options shown below does not follow the application of reflection of sound?

Reflection of sound refers to the phenomenon in which sound waves bounce off a surface and change their direction. This phenomenon is utilized in various devices for different purposes.

Stethoscope: A stethoscope is a medical instrument used by doctors to listen to sounds produced by internal organs. It uses the reflection of sound to transmit the sound waves from the patient's body to the doctor's ears.❌

Tape recorder: A tape recorder is a device used for recording and playing back sound. However, the tape recorder itself does not rely on the principle of reflection of sound to function. It primarily operates based on the conversion of sound waves into electrical signals and vice versa.✅

Megaphone: A megaphone is a device used to amplify sound and project it in a specific direction. It works by reflecting and focusing sound waves, allowing them to travel in a concentrated beam.❌

Speaker: A speaker is an audio device used to produce sound. It utilizes the principle of reflection to create sound waves.❌

Therefore, "Tape recorder" does not follow the application of reflection of sound.
