What are two main bands of television wave frequencies?
Amplitude and frequency
What type of electromagnetic wave is used for TVs?
The type of electromagnetic wave used for TVs is radio waves. Specifically, TV signals are carried on radio frequencies within the electromagnetic spectrum.
Why is it possible to transmit TV signals by ground wave propagation?
Ground wave propagation for TV signals is possible because the signals use low frequencies that can travel along the Earth's surface, following its curvature. This allows the signals to reach receivers beyond the line of sight. Additionally, ground waves experience less attenuation compared to higher frequencies, making them suitable for long-distance transmission.
What units are wave frequencies measured in?
Wave frequencies are typically measured in hertz (Hz), which represents the number of cycles per second.
What is the definition of ocilator?
An oscillator is an electronic circuit that produces a repetitive electronic signal, typically a sine wave, square wave, or sawtooth wave. Oscillators are commonly used in electronic devices such as radios, televisions, and computers to generate clock signals, audio tones, and radio frequencies.

Are TV broadcast signals sent by microwaves?
Yes, TV broadcast signals are typically transmitted using radio waves, which are a type of electromagnetic radiation. Within the radio wave spectrum, there are various frequencies, including microwaves, that can be used for transmission. However, standard TV broadcasts generally utilize frequencies in the VHF (Very High Frequency) and UHF (Ultra High Frequency) bands, which are lower than microwave frequencies. Therefore, while microwaves can be part of the transmission process, traditional TV signals are not solely sent by microwaves.
What type of electromagnetic wave is used for TVs?
The type of electromagnetic wave used for TVs is radio waves. Specifically, TV signals are carried on radio frequencies within the electromagnetic spectrum.
Frequency of radio wave for RFID tags?
Depends on where you are. Each nation has its own rules. There are legal frequencies in the 125 KHz, 13.56 MHz, 800-950 MHz, and 2.4 MHz bands. Higher frequencies are coming.
Can A standing wave can only occur at natural frequencies?
A standing wave can occur only at specific frequencies that are called natural frequencies.
Why is it possible to transmit TV signals by ground wave propagation?
Ground wave propagation for TV signals is possible because the signals use low frequencies that can travel along the Earth's surface, following its curvature. This allows the signals to reach receivers beyond the line of sight. Additionally, ground waves experience less attenuation compared to higher frequencies, making them suitable for long-distance transmission.
What is the main difference between radio wave and a light wave?
The difference is their wavelengths. That means that their frequencies are different, and also the amount of energy carried by each photon.
What electromagnetic spectrum is used for radio broadcasting?
Radio wave brings the information into the TV set from which the sound and pictureare reconstructed.Light wave carries the picture ("video") information from the screen to your eyes.
What units are wave frequencies measured in?
Wave frequencies are typically measured in hertz (Hz), which represents the number of cycles per second.
A wave with which frequencies would have the shortest wavelength?
a wave with the highest speed

Is a microwave a type of infrared wave?
yes so is am fm radio and tv signals
