Two examples of sound waves are transverse waves and longitudinal waves. Students can visualize transverse waves as ripples on a pond and longitudinal waves the movements of a slinky.Continue Reading
Sound waves are created by the vibration of an item, which then produces a pressure wave that displaces the air. The displacement vibrates the ear drum in the ears and is registered as a sound by the brain.
Sounds waves can pass through mediums such as air, water, gases and solids. Longitudinal waves will go through compressible mediums, while transverse waves go through solid objects such as wood. However, the particles within the medium do not travel with the sound wave.Learn more about Motion & Mechanics
Radio waves are used to receive and transmit signals between two objects. These waves help to transfer signals from broadcasting stations to televisions and radios, and they are also used to transmit signals for cellular phones.Full Answer >
Because sound energy is created by mechanical waves vibrating through matter, the steady oscillations of sound gradually convert to internal energy of the molecules they vibrate, such as air molecules. A sound stops being audible because its energy has been absorbed by the medium through which it travels.Full Answer >
Some examples of pulleys are cranes and flagpoles. Both cranes and flagpoles have a pulley at the top of their poles.Full Answer >
Some examples of resonance are a pendulum, a playground swing, a tuning fork and a human voice at a pitch sufficient to shatter glass. Resonance is a vibration system or external force driving another system to oscillate with greater amplitude at a specific preferential frequency.Full Answer >
