Sound energy is a form of energy created by vibrations that travel as waves through a medium, producing audible or inaudible sound.

1. Sound is created when objects vibrate and produce waves.


2. Sound moves in waves, called compression and rarefaction.


3. Sound must travel through air, water, or solids and cannot move in space.


4. Sound moves fastest in solids, slower in liquids, and slowest in gases.


5. The highness or lowness of a sound depends on the frequency of the waves.


6. How strong or weak a sound is depends on the wave's amplitude.


7. Sound can bounce off surfaces, causing echoes.


8. Soft materials can soak up sound, reducing noise.


9. Sound bends around obstacles or spreads through small openings.


10. Humans can hear sounds between 20 Hz and 20,000 Hz.

1. Sound is used for transmitting information between people or devices.


2. It is essential in music, movies, and other forms of recreation.


3. Sound alerts people to danger through alarms or signals.


4. It helps determine direction and location.


5. Sound aids in diagnosis and treatment, like in ultrasound technology.


6. It is used to monitor machines and detect faults.


7. Sound enables learning through speech, lectures, and audio materials.


8. Sound energy helps in studying physical phenomena and environments.
