does fire have shadows? if yes, how? and can u prove it?

Question

Hi Everyone! This is trickster.

This is one of those q's that can be debated till the End of the World and still not reach a definite conclusion. That's why I had asked for some sort of proof that supports your answer.

Thank you 'pretzels', for sharing the results of your experiment with everyone here. And thank you all for your participation.

Answer 1

Wow!!! This is the best questions ever. I've answered hundreds of questions but this is the first one that made me run out in the garage and do an experiment.

To have a shadow, the flame must absorb light, nothing else is required. By absorbing light, it will create a dimmer region on the screen behind it than the surrounding area.

To actually see the shadow takes more. The light source must be a bright enough to overcome the light of the flame so that the light cast by the source can give you enough contrast. The light source also need to be far enough away (or have parallel rays) to give you a reasonably sharp image. Getting these things to work together is tough.

I used a candle and a 150 watt halogen work light. There is some trade off on where to put your screen (a sheet of paper is fine) to see the shadow. If it is too far from the flame, the shadow gets too fuzzy and washed out. If its too close, the light from the flame washes out the shadow. Similarly, if the light it too close to the flame, the shadow is too fuzzy to see. To far away and it is too dim.

My 5 minute experiment did give me a shadow but a faint one and then only of the tip of the flame. Try it! It's real science in action!

Answer 2

Shadows can be observed but have no physical existence. They simply represent a shape that is hidden from light.

Since fire is a light source, it would be responsible for the appearance of shadows on the other side of surrounding objects because it spreads light on all sides of those objects.

If you have a very strong torch that you direct on a flame, the flame may appear as a shadow on the background since it sends less light.

Conclusion note: Always try to use positive logic and avoid negative logic because it just makes things more complex for nothing. (Shadows don't exist in physics, the surrounding lighted areas do!)

Answer 3

Fire it self does not have a shadow because the flames are made of light... Heat does not create a shadow eather the quimical reaction involed in a fire will not allowed. Good Question EFIL

Answer 4

Yes, any light gives off a shadow. Light a candle and you'll be able to see the shadow.

Answer 5

Fire has shades. It is brighter where the temperature is higher.

It doesn't have shadows though. It creates light and light creates shadows. Light itself cannot have a shadow.
