I also learned that ????????
SUN: I found it incredible that ???? and I liked learning about...

I can't wait to read all your interesting comments later!]]> 2016-02-08 17:04:52 UTC https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93848618 https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93987682 did you know that rainbows use refraction to show nearly all the diffrent colors because when you mix red, orange, yellow, green, blue, indigo and violet it makes white and when you shine it through a prism the colors will blend and you'll see all the colors.]]> 2016-02-09 09:17:51 UTC https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93987682 https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93987717 light
how do we see light and how does it bounce?
When light from a light source lets out its light, then the light bounces on an object then your eyes catch this reflected light which allows you to see.

How fast can light travel?
Light can travel 300 million meters in one second.
How does a mirror work?
If you hold up a mirror it bounces right back at you]]> 2016-02-09 09:18:06 UTC https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93987717 https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93987728 the word laser stands for light 
amplification by
stimulated
emission of
radiation.
laser light comes from lasing medium. it can be a gass liguid solid or gass.when the attoms have absorbed the energy they have to relees the energy in the form of a photon.

I learned more about refraction because I did not get it 100% with Mr Rea.
Now I am more confident.
So what i learned was that  light slows down if somewhere is more dense.
Also I learned that diffraction is when light spreads out for example if I yell something across the room bunch of sound waves come out of my mouth.
Second video: Telescopes!!!
I learned that we see things sometimes smaller that it is that is why we have telescopes. Telescopes capture and magnify light.

I wonder if whe efect would be the same if it was a stream of water not just drops?

electromagnetic spectrum:
there are 7 different types of electromagnetic spectrum they are radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays and gamma rays. radio waves are used for TV radio  and stars can also collect those signals. am uses low signals]]> 2016-02-09 09:19:11 UTC https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93987882 https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93987907 Light:
 Animals can produce light through chemical reactions. One of the animals that can  is anglerfish.

Light can travel 300 million meters per second.

Rainbow:
When you mix red, orange,yellow,green,blue,indigo and violet light you get white light.

Rainbows show up when sunlight bounces off of the water in the air.]]> 2016-02-09 09:19:21 UTC https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93987907 https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93987958 Rainbows use refraction to show the different colors because all the colors in the rainbow make white if you mix theme together but if you you shine it through  triangular prism the color will bend so you can see the different colors. A rain drop is like a triangular prism.

The movie also shows how we see  the light bounces of your eyes and you can see everything around you.]]> 2016-02-09 09:21:32 UTC https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93988244 https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93988302 refraction is were light slows down and bends through an object

I wonder what the deal with refraction is?

Rainbows
Whay are there so many songs about rainbows?]]> 2016-02-09 09:23:05 UTC https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93988498 https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93988997 different colours of light have different angles of refraction.

You can never get to the end of a rainbow because a rainbow is sunlight coming from behind you, bouncing off of water in the air in front of you. A rainbow is really just an optical effect, not an actual object.

The electromagnet spectrum is the name for a bunch of types of radiation including visible light. like all waves, light waves have a wavelength. Some of the electromagnet waves are radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays.     ]]> 2016-02-09 09:26:10 UTC https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93989066 https://padlet.com/harrydalzell81/cy5rqdkuglf3/wish/93989247 Light can act like a wave some times.
Stars that we see have to travel thousands of years before it reaches us.
Light can travel 300 million meters in one second.
When light goes from a material to another, it bends or refracts.
It bends because light goes through diffrent materials in different speeds. 
Light can travel much quicker going through air than it can through glass.
