Can a fire cast a shadow?
There doesnât seem to be a shadow casted on the wall in the above image of a burning matchstick. So, does that mean that fires donât cast shadows at all?
One common argument that follows is:
Fire is a source of light, hence cannot cast a shadow
But, that arguments falls apart, when you realize that:
Sure, fire is a source of light but it is not the brightest
                                                Source
Fire could cast a shadow, if the light source behind the fire was brighter than the flame itself.
You can simply use an iPhoneâs flashlight and a lighter. The LED from the iphone is just powerful enough to begin to make a shadow from the flame.

Go ahead, try it! Have fun!
** Food for thought :
Why does this phenomenon occur when the light source behind the flame is brighter ?
I could reveal the answer, but Its even better when you think about it and comprehend it for yourself. Wouldnât want to deprive you of that excitement , now would I ?
