Interesting experiment

In the evening, I took a candle on the window sill and my dad lit it with a lighter. I held a candle, dripped the wax oil into the plate, put the lit candle in it and glue it, then lifted the plate in front of the mirror, but I found that the candle was not as bright as the book said, just a little Bright light. I placed the plate in front of a small mirror and found that the light of the candle was weaker. I put the plate in front of a small, not too small mirror. Although the candle was brighter than the previous two, it was still not so bright.

I did this experiment a total of three times, and the effect was not ideal. I think the main reason may be that the number of candles is too small. If you can have more, it will be fine.
