The study of sound & sound waves-

Correct option is C

Explanation:

The study of sound and sound waves is known as Acoustics. It is a branch of physics that deals with:

• Production,
• Transmission, and
• Effects of sound waves in various media such as air, water, and solids.

Acoustics helps in understanding not just how sound travels, but also how it can be controlled and used in real-world applications, like in architecture, music, sonar, medical imaging (ultrasound), and even noise control.

Information Booster:

The term “acoustics” comes from the Greek word akoustikos, meaning “of or for hearing.”

Applications of acoustics include:

• Designing concert halls and auditoriums
• Noise cancellation technologies
• Ultrasonic cleaning and imaging
• Seismology (study of Earth’s vibrations)
