Yes.
Not all antennas require a specific length. However, some antennas (and antenna elements) have a length corresponding to the wavelength of the electromagnetic wave being detected: radio, television, shortwave, and so forth.
Ground-dependent antennae refer to antennas that require a physical connection to the ground in order to function optimally. These antennas rely on the ground plane to radiate or receive radio signals efficiently. Ground-dependent antennas are commonly used in mobile communication devices and radio systems where a connection to the ground plane can be established.
High frequency is used because of the the size of antennas used to transmit and receive the communications signal. The higher the frequency the smaller the antenna.
The frequency formula used to calculate the resonance frequency of a tuning fork is f (1/2) (Tension / (Mass per unit length Length)), where f is the resonance frequency, Tension is the tension in the tuning fork, Mass per unit length is the mass per unit length of the tuning fork, and Length is the length of the tuning fork.
Stride Frequency= # of Stride/ time. the unit used is strides/sec Stride Length= speed/stride frequency. the unit used is m/stride
You can use an inductor or capacitor circuit to electrically lengthen or shorten the antenna. I cant remember which circuit does which but that's how antennas are efficiently used for several frequencies.
A synchronous motor is used only with a.c. Its speed is dependent on the frequency of the a.c.
Speed = Frequency * Wave length.
Television signals primarily rely on electromagnetic waves within the radio frequency range, specifically UHF (Ultra High Frequency) and VHF (Very High Frequency) bands. These waves are used to transmit audio and video information to TV antennas for reception by television sets.
The equation used to determine the velocity of a wave is: velocity = frequency x wavelength. This equation shows that the velocity of a wave is dependent on the frequency of the wave and its wavelength.
three basic types of antennas are: omnidirectional; semidirectional and highly directional antennas. typically when you purchase wireless access point and wireless NIC it has attached 2.14dbi omnidirectional antennas
To send multiple messages by changing the carrier signal. To be able to use smaller antennas higher frequency means smaller antenna
