hello world today i am going to tell you about light
natural light vs artificial light
natural light is light that is not made by a person for example sunlight, glow worms, oil lamps, and fireflies.
artificial light is light that is made by a person for example fireworks, glow sticks, candles, and light bulbs.
Emitting and reflecting light
emitting light means luminous . luminous means giving off light for example ,sunlight tv, the moon candles, and stars. reflecting light means nonluminous. nonluminous means we can only see objects that are reflecting the light from other sources.
experiment 1 how does light travel ?
in my first experiment we saw how light travels . light travels in a line and reflets of of things . the materials were paper flashlights and clay. we poked a hole in the paper and on the last one there was a x for a target we lined the paper up and shined the light though and it hit the target.
experiment 2 what makes a good reflector ?
reflection means light that shines on to something shiny good reflective materials are mirrors, tinfoil, and a window. we did a experiment looking at what makes a good reflector we used materials . like mirrors , and flash lights.
transparent translucent opaque
we did a experiment on transparent translucent and opaque the materials we used are paper and plastic. for example transparent is windows a example for translucent is tissue paper and a example for translucent is a wall.
refraction
