Hello, this is my blog post about light, I hope you like it!
Artificial sources of light versus natural sources
We/my class sorted out manmade sources of light versus natural sources.
down here is manmade sorces of light, and below it, is natural.
Artificial sources of light: glowsticks, fireworks, lightbulbs, candles, oil lamp.
Natural sources of light: fireflies sunlight glow worms.
Objects that emit light, Objects that reflect light
This time we sorted out objects that emit light and one that reflect light.
These are the ones we sorted.!
Light emitters: HDTV, candle, sunlight, moon, star.
Light reflectors: table, water bottle, bowling shoes.
also here a random fact luminous means something that emits light and non-luminous means a random object that doesn’t
Experiment 1: In the first experiment we lined up cards with holes in the middle except for one in the back because that
one had a target on it but we shined a flashlight at the cards and hoped it hit it, and sure enough it went through!
Experiment 2:What makes a good reflector?
I did an experiment about reflecting a flashlight at different things such as glass, tinfoil, crumpled tinfoil, black paper,
white paper, and green paper.
the best reflector was crumpled tinfoil and the worst was
black paper.
