Hello, world!! today I will be talking about natural light 

Natural light vs. Artificial light

the first thing I will tell you about is natural and artificial light. we learned about lots of examples of it including oil lamps fireflies, and so on and so on. Natural means it naturally occurs, and artificial means it is man-made. In the 1500s they used natural light because they had no electricity now, they use artificial light like electricity. I bet you can name some artificial light sources that you are using right now.

now I will be telling you about…                       Reflecting and Admitting light

Examples

The first thing I will tell you about is a few examples of stuff that reflect light like cars, metals, water bottles, and food. Stuff that admits light is lights, stars computers, TVs, and ipads.

 

What It Means

reflecting and admitting light is an object that admits light, which means it gives out its own light. an object that reflects light means light bounces off of it. you can probably name some of them.

 

 

Opaque Translucent and Transparent

 

Opaque

Opaque means no light can travel through the object.

 

Translucent

Translucent means some light can pass through the object.

 

Transparent

Transparent means all light can pass through the object.

 

 

 

 

5 Facts About Light

Light travels 186,000 miles per second.

Light can travel around Earth in 0.1337 seconds.

It would take 37,200 years to travel 1 light year.

Did you know Not even light can escape a black hole?

Did you know that light is the fastest thing to ever exist?

 

 

 

refraction!!

Refraction is the bending of light the speed of the light that passes through a medium. a medium is the thing that light travels through. in class, we did an experiment on light we used a coin and a pencil. first, we put the pencil in the water and realized it looked like it was cut in half. then we put the coin in the water and it looked a lot bigger than it did when it was in the air.
