What is the wave in which amplitude changes to create sound?
The wave in which amplitude changes to create sound is called an acoustic wave. As the amplitude of the wave increases, the sound produced becomes louder, and as the amplitude decreases, the sound becomes softer. This change in amplitude is what creates the variations in volume or intensity in sound waves.
Is it true that in phenomenon known as the Doppler effect electric current will flow when light shines on certain substances?
It is not true that the Doppler effect has anything to do with electricity and the flow of current. The Doppler effect involves pitch and sound frequency of moving objects, for example the apparent noise changes of an approaching car.
What part of a sound wave changes as its energy decreases?
The amplitude of a sound wave changes as its energy decreases. Amplitude corresponds to the perceived loudness of the sound. As energy decreases, the amplitude of the sound wave decreases, resulting in a quieter sound.
Can an electric current generate an electromagnetic wave?
Not a constant electric current but a changing one will generate electromagnetic waves.First: If you have a lone electron, and it is accelerated in any way, it will send off an electromagnetic wave. This is because a changing electric field generates a magnetic field.It is also true that changing magnetic field will generate an electric field. This is the reason that if you have an electric current, which is generating a magnetic field, and you change the current you generate an electromagnetic wave. To generate a continuous sinusoidal electromagnetic wave you continuously change the current sinusoidally.
Is the amplitude of a wave changes what changes?
If the amplitude of a wave changes, the wave's intensity, energy, and loudness (in the case of sound waves) would also change. The wavelength and frequency of the wave remain unaffected by changes in amplitude.
Can a sound wave produce a magnetic field?
sound wave cannot produce magnetic field because magnetic field is created due to flow of electric currents sound is a mechanical wave, sound is produced due to vibration in a medium so sound wave cannot create electric current or magnetic field
What kind of wave in which amplitude changes to create sound?
The type of wave in which amplitude changes to create sound is a sound wave. Amplitude is the measure of the changes within the wave.
Does earphones change electric current to sound wave?
Yes, ear buds and headphones are miniature speakers.
What is the wave in which amplitude changes to create sound?
The wave in which amplitude changes to create sound is called an acoustic wave. As the amplitude of the wave increases, the sound produced becomes louder, and as the amplitude decreases, the sound becomes softer. This change in amplitude is what creates the variations in volume or intensity in sound waves.
Is there sound that travels in currents?
No, sound is a wave not a current.
What property of a sound wave changes when a sound gets soft?
The amplitude of a sound wave is perceived as the sound's loudness.
What is a wave that consists of changing electric and magnetic fields called?
Sound wave
Is it true that in phenomenon known as the Doppler effect electric current will flow when light shines on certain substances?
It is not true that the Doppler effect has anything to do with electricity and the flow of current. The Doppler effect involves pitch and sound frequency of moving objects, for example the apparent noise changes of an approaching car.
Which type of device emits a sound wave?
First you convert the sound into a modulated electric current using a microphone, then you convert the modulated electric current into a visible pattern using an oscilloscope.
What part of a sound wave changes as its energy decreases?
The amplitude of a sound wave changes as its energy decreases. Amplitude corresponds to the perceived loudness of the sound. As energy decreases, the amplitude of the sound wave decreases, resulting in a quieter sound.
