We just learned about this in science class. Air vibrates throughout the tube part and out the bell to produce sound waves.
Musical instruments have some part that vibrates at a regular frequency. This vibrating part makes the air around it vibrate and these vibrations make the sound waves. The part that vibrates is often a string or a reed or a drum-head or in the case of horns, the player's lips. The vibrations are amplified by a column of air or a sounding board or something else that resonates at the frequency produced by the original vibration.
In a stringed musical instrument, the part that vibrates in resonance with the sound waves produced by the strings is called the soundboard or the resonating body. This part amplifies and projects the sound created by the vibrating strings to produce audible music.
In a radio, it is the speaker that vibrates to create sound. The electrical signals from the radio's circuitry are converted into physical vibrations by the speaker's diaphragm, producing audible sound waves.
the string, and the waves go into the body and reverberate around, and come out the f holes and make the sound.
The sound waves come through the auditory canal and hit the eardrum (or tympanic membrane). The eardrum is connected to the 3 ossicles of the middle ear: the hammer, anvil and stirrup (or malleus, incus and stapes). The eardrum vibrates the hammer, the hammer vibrates the anvil, the anvil vibrates the stirrup and the stirrup vibrates the cochlea in the inner ear which has hair-like nerve endings called cilia that move when the cochlea vibrates. The auditory nerve sends the vibrations to the brain to be interpreted. That's how we hear! :)
The strings.
The tympanic membrane, also known as the eardrum, is the part of the ear that converts sound waves into vibrations. When sound waves reach the eardrum, it vibrates and transmits these vibrations to the middle ear.
The wavelength of a sound wave in water with the same frequency as the electromagnetic wave would be different since sound waves and electromagnetic waves propagate differently. In general, sound waves in water have shorter wavelengths compared to electromagnetic waves. The specific calculation would depend on the frequency provided in "part B."
The eardrum (tympanic membrane) vibrates in response to sound waves entering the ear canal. These vibrations are then transmitted to the small bones in the middle ear, which in turn amplify and transmit the sound to the inner ear for further processing.
The membrane of tabla vibrates to produce a sound.
The vibrating part of a loudspeaker is the diaphragm or cone. It is responsible for converting electrical signals into sound waves by vibrating back and forth to produce audio frequencies.
