Any body that gets hot enough will radiate light. The sun for example behaves like a black body at about 6000 degC, but that is not a sensible or economical process to copy for artificial light, which we can make using electrical energy. The filament in an incandescent light bulb is producing light because it is at a high temperature in a suitable gas, but there it is converting electrical energy not thermal. To convert thermal energy directly to light, you only have to think of a candle, there the hot flame is producing the light. This is refined in the old fashioned oil lamp. I recall these being used in rural areas before electricity was laid on. There is a reservoir for the burning oil, a pure form of kerosene, a wick and a mantle which gets very hot and radiates the light. A modern version used for camping has a small butane container attached to provide the thermal energy input to the flame and mantle.

What is a device to convert electron flow to another form of energy?
A device that converts electron flow into another form of energy is called a transducer. Transducers can convert electrical energy into mechanical, thermal, or optical energy, among other types. Examples include speakers (electrical to acoustic energy), light bulbs (electrical to light energy), and electric heaters (electrical to thermal energy).
When a cellphone is turned on what energy are formed?
When a cellphone is turned on, electrical energy is used to power on the device and convert it into the various forms of energy required for its functioning: radio frequency (RF) energy for communication with cellular networks, light energy for the screen display, and thermal energy due to the device's internal components operating.
How do you convert thermal energy into radiant energy?
Thermal energy can be converted into radiant energy through a process called thermal radiation. When an object's temperature increases, it emits electromagnetic radiation in the form of visible light, infrared, or ultraviolet radiation. This conversion is based on the object's temperature and its emissivity properties.
How do you convert light to thermal?
Light can be converted to thermal energy through absorption by a material, which causes the material's molecules to vibrate and generate heat. This process is known as photothermal conversion and is used in solar thermal systems to convert sunlight into heat energy for various applications such as heating water or generating electricity.
What is the tendency for a material to oppose the electron flow and change electrical energy in to thermal energy and light?
The tendency for a material to oppose the flow of electrons and convert electrical energy into thermal energy and light is known as resistance. This property is determined by the material's resistivity and is quantified in ohms (Ω). The higher the resistance of a material, the more it will convert electrical energy into heat and light.

What energy does a refrigerator convert to?
thermal nd light.

What are 2 forms of energy that may be absorbed?
Two forms of energy that may be absorbed are light energy, such as from the sun, and thermal energy, which is heat energy. When an object absorbs light energy, it can convert it into other forms of energy, like heat.
Is mechanical energy coming from light and heat?
Mechanical energy does not come directly from light and heat. Light and heat are forms of energy, but they do not typically convert into mechanical energy. Mechanical energy is typically associated with the motion or position of an object.
What is a complete energy transformation sentence for a campfire?
t Campfires convert chemical energy stored in wood into thermal energy, which is useful for cooking food and staying warm.
How is chemical energy transformed into thermal energy in a solar oven?
In a solar oven, the sunlight is absorbed by a dark surface inside the oven. This absorbed light energy is then transformed into thermal (heat) energy, causing the interior of the oven to heat up. The dark interior of the oven helps to efficiently convert the light energy into thermal energy.
What changes electric energy into other forms of energy?
Electric energy can be changed into other forms of energy by devices such as electric motors, which convert electrical energy into mechanical energy; light bulbs, which convert electrical energy into light and heat energy; and electric heaters, which convert electrical energy into thermal energy.
How do we generate thermal energy?
Thermal energy is simply heat. Light a fire.
