What motion in a transmitting antenna causes the vibrations that produce radio waves?
The oscillating electrical current in the antenna causes the electrons in the antenna to accelerate back and forth, creating electromagnetic waves that propagate as radio waves. This motion generates a changing electric field that propagates through space at the speed of light.

What speed of vibration causes a pitch to be high or low?
Higher frequency vibrations result in a higher pitch, while lower frequency vibrations produce a lower pitch. The pitch of a sound is determined by the frequency of the vibrations in the air.
Why a spoon can sound like bell explain?
When a spoon is struck against a hard surface, it causes vibrations in the metal of the spoon. These vibrations travel through the air as sound waves, which our ears detect. Depending on the material and shape of the spoon, the vibrations can produce a ringing sound similar to that of a bell.
How vibrations affect an object and produce sound?
When an object vibrates, it causes air particles around it to also vibrate, creating sound waves. These sound waves travel through the air until they reach our ears, where they are interpreted by our brain as sound. The pitch and volume of the sound depend on the frequency and intensity of the vibrations.
How is sound energy carried?
Sound energy is carried through vibrations in a medium, such as air, water, or solid objects. When an object vibrates, it causes the particles in the medium to move in a wave-like pattern, transmitting the sound energy from the source to our ears.
What sets sound in motion?
Sound is set in motion by vibrations in a medium, such as air, water, or solids. When an object vibrates, it causes the surrounding particles in the medium to also vibrate, transmitting energy in the form of sound waves. These sound waves then travel through the medium until they reach our ears and are interpreted as sound.
Does listening to an orchestra produce vibrations?
No, the act of listening does not produce vibrations, unless you mean that being exposed to sound causes vibrations in your tympanic membrane. That is a part of the mechanism of hearing. Hearing and listening are two different things.
What speed of vibration causes a pitch to be high or low?
Higher frequency vibrations result in a higher pitch, while lower frequency vibrations produce a lower pitch. The pitch of a sound is determined by the frequency of the vibrations in the air.
What causes volume?
Vibrations.
What causes a fault?
vibrations
Why antenna is a sensor of EM waves?
The transmitter sends out EM waves. EM waves are a carrier of energy and are produced by oscillating charges - usually caused by connecting metal to AC power supply. The waves travel through a medium and transfers its energy to the antenna which is basically a metal rod. The energy causes charges in the metal to oscillate at a certain frequency, controlled at the transmitting end. The charges oscillate to produce corresponding EM waves which can be detected/read as signals and turned into sound energy etc...
Do shorter strings produce longer notes?
The reason that they create longer notes is because it vibrates faster, but not as big vibrations, which causes the pitch to be higher, and also can vibrate longer.
When the air rushing in hits your voicebox it causes?
vibrations
What is sound and how it is produce?
Sound is vibrations in a physical medium (usually air). Sound is produced by a release of energy that causes a vibration in the medium. Sound can not therefore be in a place where there is no medium (empty space).

What causes the air inside a trumpet to vibrate?
the vibrations from your lips
What structure vibrates the malleus?
The eardrum (tympanic membrane) vibrates in response to sound waves, which in turn causes the malleus (hammer) bone to vibrate. The malleus is connected to the eardrum and transfers these vibrations to the other ossicles in the middle ear, ultimately transmitting the sound to the inner ear for processing.
How do you check to see if your antenna is too short?
A short antenna causes higher than normal current to capacitive reactance and a long antenna causes higher than normal current to inductive reactance; a correct length antenna is free of reactance and appears as a resistance. Change the length of the antenna in small increments until you obtain the lowest (resistive) current.
