How Stuff Works explains that sound travels in mechanical waves, and these waves are disturbances that cause energy to move. The energy is then transported through a medium. Disturbances occur when an object vibrates. This vibration is caused by interconnected and interactive particles.Know More
Sound has the ability to travel through gases, liquids and solids. How Stuff Works sates that the speed of any sound wave is highly dependent on the medium through which it travels. The speed of sound is greater when it travels through solids. It travels more slowly when it goes through liquids and gases. This means that the denser the medium through which sound travels, then the slower it passes. This is evidenced by the fact that sound travels faster on a warm day than on a cold day.
The sounds that one hears are created when air particles collide. These air particles pass from the object the sound is coming from into the eardrum, which is also known as the tympanic membrane. This movement of sound waves from the object to one's eardrums is called transmission. How Stuff Works explains that when the air particles collide with the eardrum, vibrations resonate through several different structures in the ear: These vibrations are sent as messages to the brain, where they are interpreted as sound.Learn more about Optics & Waves
Sound waves transfer energy by causing successive compressions and rarefactions in the particles of the medium without transporting the medium particles themselves. Sound in solids can also manifest as transverse waves, causing crests and troughs in the propagation medium.Full Answer >
Sound occurs as a result of the back-and-forth vibration of sound waves travelling across a medium. A sound wave is sometimes referred to as a pressure wave because it contains repeating patterns of high-pressure and low-pressure regions.Full Answer >
Ultrasonic sound waves are waves of sound beyond the range of perception. These sound waves are used by bats and dolphins for navigation and by medical imaging and in non-destructive testing.Full Answer >
Music, speech and explosions are all examples of sound waves. Sound waves are mechanical vibrations in a compressible medium. The larger the amplitude of the waves, the louder the wave sounds. Because mechanical vibrations require a medium to vibrate, sound does not manifest in vacuums, such as space.Full Answer >
