Power, in all situations is the rate of change of energy. If the power is constant, it can be found using the formula, "Power = Energy Used / Time taken". So, the power of a radio wave (in watts) is equal to the amount of energy it transmits (in joules) per second.
In symbols:
P = E/t

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 is the difference in a philips portable radio and a standard radio?
The difference between a Philips portable radio and a standard radio are that a Philips radio is battery powered, while a regular radio is electrically powered.
Can heat energy released by an animal can power a radio?
no
Heat energy released by an animal can power a radio.?
no
What type of energy is in a radio stereo?
well it is run on power so it is not energy
What forms of energy does a radio use?
A radio typically uses electrical energy to power its circuits and components. The radio then converts this electrical energy into sound energy through its speakers to produce sound waves that we can hear.
How did the energy transform for a battery powered radio?
In a battery-powered radio, chemical energy stored in the battery is transformed into electrical energy when the battery provides power to the radio's circuitry. This electrical energy is then transformed into sound energy and electromagnetic energy (radio waves) as the radio converts the electrical signals into sound waves that we can hear.
What is a radio waves energy?
(The power of the radio transmitter) times (the length of time it continues to transmit)
What source of energy a radio uses?
A radio typically uses electrical energy from a battery or power outlet to function. The electrical energy powers the components inside the radio, such as the circuitry, speaker, and tuning mechanisms, allowing it to receive and amplify radio signals to produce sound.
What is the difference between ultrasonic welding and radio frequency welding?
what is the difference between ultrasonic welding & radiographic welding
What energy is stored in a radio?
A radio stores electrical energy in its batteries or power source, which is converted into sound energy to produce sound waves that transmit information. Additionally, a radio may also store potential energy if it has an antenna that can capture radio waves from the air.
What energy transformations take place in a radio?
In a radio, electrical energy from a power source is converted into electromagnetic energy (radio waves) by the transmitter. The radio's antenna captures these radio waves and converts them back into electrical signals, which are then converted into sound waves by the speakers, thus transforming the energy back into sound energy for us to hear.
