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
The most basic characteristics of a sound wave are pitch, loudness and tone. A sound wave's frequency is experienced as the wave's pitch. The amplitude determines loudness or volume. The tone of a sound wave can be recognized by the regularity of its vibration.Full Answer >
The three aspects of sound waves are wavelength, frequency and amplitude. Wavelength describes the distance between each sound wave, and frequency relates to the number of waves counted in a specified amount of time. The energy in a sound wave is called amplitude.Full Answer >
Mechanical motion forms through the sound waves made by vibrating massive objects. Guitar, harp or piano strings are clear examples of the principle, but horns, percussive instruments and woodwinds also create vibrations that make sound waves. Even ordinary objects create sound waves if they vibrate.Full Answer >
Sound waves can be reflected. They most often reflect when they hit an obstacle in their path, such as a hard wall. Some sound waves will be reflected when the sound transitions from traveling through one medium to another, such as going from air to water.Full Answer >
