What's the difference between flame (due to fire) and photons?
A flame is a visible, luminous gas that is the result of a chemical reaction, typically between oxygen and a fuel source. Light, on the other hand, is a form of electromagnetic radiation that can be seen by the human eye.
A flame is created when a fuel source (such as wood or gas) is heated to a high enough temperature, causing it to release gases that react with oxygen in the air. This reaction creates a visible flame.
Yes, a flame emits light in the form of visible electromagnetic radiation. However, not all forms of light are flames, as light can also be produced by other sources such as electricity or the sun.
The color of a flame depends on the temperature of the fuel source and the type of fuel being burned. For example, a blue flame typically indicates a hotter temperature, while a yellow flame is usually cooler. Different chemicals can also produce different colored flames, such as the green flame produced by burning copper sulfate.
No, a flame cannot exist without producing light. However, the amount of light emitted by a flame can vary depending on the fuel source and other factors such as oxygen levels and temperature.
