i was just wondering how light comes to be, from light bulbs or flash lights...
is it energy transferred through the particles in the air?

I'm still new to physics and am curous about this :tongue:

An Electric field is applied to the wire and electrons start to flow and they flow through the filament and while these electrons are flowing they have all these collisions inside the material and that produces heat, And the tungsten filament starts to glow red and then eventually glows white hot producing white light. The light is cause by vibrating electrons in the material. And then particles of light called photons are shot off like little bullets from the light bulb. Light is produced from oscillating charged particles. We have to be careful, light is a little more complicated than little bullets tho.

i think i got the concept, thanks cragar :)

Since the OP's question is answered, let me use this thread for a related question.

Does the electrons deep inside the material contribute to the light emission, or it is only the peripheral atoms? Let me think aloud: an inside electron created a visible light particle, but the material is opaque to light. The surrounding atoms (still deep inside the material) receive the light and converts it into heat energy. The heat energy causes it to emit more light. Such millions of (depending on the number of atoms in the material) heat<>light conversions happen before we see the light outside. Am I correct?

Hello there,

That's a great question! Light is a form of electromagnetic radiation, which means it is made up of electric and magnetic fields that travel through space. When we turn on a light bulb or a flash light, we are essentially creating a flow of electricity through a filament or a battery, which then excites the atoms in the bulb or flashlight and causes them to emit light. This process is called incandescence.

In the case of a light bulb, the electricity flows through a thin tungsten filament, which has a very high melting point. As the electricity passes through the filament, it heats up the tungsten and causes it to emit light. In a flashlight, the electricity flows through a battery and then through a thin wire called a filament, which is coated with a material that glows when heated.

So, to answer your question, light is not transferred through particles in the air, but rather it is created by exciting the atoms in the light source and causing them to emit light. I hope this helps to clarify things for you. Keep exploring and asking questions about physics - it's a fascinating subject!
