What else can I help you with?
When a light bulb is lit electrical energy is changed into light energy and?
heat energy. The electrical energy powers the light emission in the bulb, producing both light and heat as byproducts of the process.
What does emission do to radiation?
Emission refers to the release of radiation from a source. This can occur in various forms such as light, heat, or particles. Emission can either increase the intensity of radiation or change its properties, depending on the source and energy involved.
How does luminescence work?
Luminescence is the emission of light from a substance not caused by heat. It can be generated through various processes such as fluorescence, phosphorescence, chemiluminescence, or bioluminescence. These processes involve the absorption of energy and subsequent re-emission of light by the substance.
What form of energy is emitted?
Energy can be emitted in different forms such as light, heat, sound, and electromagnetic radiation like X-rays or gamma rays, depending on the source and the process involved in the emission.
Does light contains heat?
Light itself does not contain heat. Heat is a form of energy that is associated with the motion of particles in a material. Light, on the other hand, is a form of electromagnetic radiation that does not have mass and does not create heat on its own. However, when light is absorbed by an object, it can be converted into heat energy.
What is the difference between incandescence and luminescence, and how do they differ in terms of light emission and energy efficiency?
Incandescence is the emission of light due to high temperature, such as in a traditional light bulb, while luminescence is the emission of light without heat, like in glow-in-the-dark materials. Incandescence is less energy efficient because it produces more heat than light, while luminescence is more energy efficient as it produces light without generating excess heat.

Is there any concerns with the electromagnetic waves associated with infrared saunas?
Heat is heat. No matter how it is generated you will make steam. It will not effect you very differently because of a different heat source. A heated rock near a fire can exhibit a similar infrared light emission as electrical radiant heat does.
How hot are luminescence?
Luminescence itself is not a measure of temperature; rather, it is the emission of light by a substance that has absorbed energy. This light can be produced at various temperatures, from very cold to very hot conditions. For instance, bioluminescent organisms can glow at ambient temperatures, while thermoluminescent materials can emit light when heated to specific temperatures. Thus, the "heat" associated with luminescence depends on the mechanism and context of the light emission.
Is the spontaneity of reactions always associated with exothermic heat release?
No, the spontaneity of reactions is not always associated with exothermic heat release. Some spontaneous reactions can be endothermic, meaning they absorb heat from their surroundings.

What does response mean in science term?
Response means reaction, as in a movement, change, or emission (like heat, light, or sound).
What is emission of energy?
Emission of energy refers to the release of energy from a system, which can occur in various forms, such as electromagnetic radiation (like light or heat) or kinetic energy. This process can take place during chemical reactions, nuclear reactions, or physical changes, where energy is transformed from one form to another. For example, in incandescent light bulbs, electrical energy is converted into light and heat energy. Emission is a fundamental concept in fields such as physics, chemistry, and environmental science.

Energy can be emitted in different forms such as light, heat, sound, and electromagnetic radiation like X-rays or gamma rays, depending on the source and the process involved in the emission.

Are stars primary sources of light?
Yes, stars are primary sources of light. They produce light and heat through nuclear fusion in their cores, which results in the emission of energy in the form of light and other electromagnetic radiation.
