Cellular phone calls are transmitted using radio waves, which are a type of electromagnetic radiation. Specifically, mobile communication relies on various frequency bands within the radio spectrum, typically ranging from 700 MHz to 2600 MHz, depending on the technology (like GSM, CDMA, or LTE) and regulatory allocations. These radio waves carry voice data by modulating the signal, allowing for communication between the mobile device and cell towers.
electromagnetic waves hope that helps :)
Cellular telephones use radio waves to transmit and receive signals. These radio waves are a type of electromagnetic wave that allows for wireless communication between devices.
Transmit heat.
Yes, all emitters transmit either a continuous wave or a pulsed waveform. Continuous wave emitters transmit a continuous stream of electromagnetic waves, while pulsed waveform emitters transmit short bursts of electromagnetic waves with periods of rest in between.
A wave is caused by a disturbance that propagates through a medium, such as water or air. Waves transmit energy and information without moving matter along with them.
When you speak into a cell phone, your sound waves are converted into electrical signals, specifically analog or digital waveforms. These electrical signals are then modulated onto a carrier wave for transmission over the cellular network. The modulation process allows the sound information to be effectively sent and received by other devices.
Electromagnetic energy
This is called a microwave and falls between the visible waves at the red end of the spectrum, and radio waves.
A mechanical wave cannot transmit energy through a vacuum because it requires a medium, such as air or water, to propagate. In a vacuum, there is no medium for the wave to travel through, so it cannot transfer energy.
