Light contains energy. You may think of it as the kinetic energy of the photons which,
according to quantum theory, are the quanta of the electromagnetic field. You may also
think of it as the energy contained in the electric and magnetic fields which make up the
light wave. This duality is a basic part of quantum theory. Which picture is the most
convenient (both are correct) depends on the experiment used to detect the energy.
If you use the photoelectric effect where the light photons bang into electrons, giving them
kinetic energy and knocking some out of the material, the photon picture is most appropriate.
If you let the light hit your skin, hoping to get a tan, or focus sunlight on a pot of water
to heat it up, the wave picture is more convenient. Then the electric field exerts an
electric force on the electrons, causing them to accelerate and gain kinetic energy. The
electric field is oscillating, reversing sign about 10^15 times per second (that is 1
followed by 15 zeros). So the electron is pushed back and forth, colliding with other
electrons and atoms in the material, heating
them up.
Battery electric energy is converted to light energy of flashlight.
Electric energy is converted to heat. The heat is then irradiated as electromagnetic waves; mainly heat radiation, i.e., infrared.
Yes, electrical energy can be changed into thermal (heat) energy. Light is electromagnetic energy, and electricity can be changed into light energy. We know that a resistance heater changes electrical energy into thermal energy. An electric range does this, as does an electric space heater. We see electrical energy changed into light in fluorescent lights.
In electric bell, electrical energy is converted int sound energy.
A lightbulb changes electrical energy to light energy
Battery electric energy is converted to light energy of flashlight.
yes... for example electrical energy is converted to heat and light energy in a light bulb
The electrical energy is converted to both heat and light energy.
Electrical energy is converted into light and heat when electric current flows through the metal filament of a light bulb.
Heat and light.
Electric energy can be converted into many things, all of them are other forms of energy. Electric energy can be converted into heat energy, like in many stoves and ovens. Electric energy can be converted into sound energy, which happens in speakers. Electric energy can be converted into mechanical energy, like with electric motors in fans and other devices. Electric energy can be converted into light energy as with a light bulb. Unfortunately, we do not currently have the technology to turn energy forms into matter as is shown in many sci-fi shows like Star Trek's replicators. Every energy is able to change its type. For example sound energy can be converted into electrical , light, heat and in many other forms.
Heat, which then produces light.
Electric Energy can be converted into many different forms of energy. The most common type of energy electricity is converted into is light energy - as with a light bulb. Another form of energy electricity can be converted into would be kinetic (motion) energy.
Because electric power energy is converted to light energy and human eyes can see light.
