Today's topic is all about LIGHT . I had to make a report about light.For my report I wrote 7 facts about LIGHT that I have learnt so far.I really liked reading and writing down all the facts.What do you know about LIGHT?Here is what I did.
What I have learnt about light
1. Light is no mass and is not really considered a matter.
2. Ultraviolet rays are rays have a very short wave
3.Ultraviolet rays can cause sun burns,To protect us from ultraviolet rays the
the O-zone,This place absorbs the ultraviolet ray and keeps it there.
4.A shadow is made when the sun is out and an object blocks the sunlight.Then there will be a black spot on ground which we call a shadow.
5.In physics, light is a type of electromagnetic radiation that is visible to the eye.
Light has the
unique property that it can be described in physics as both a wave and as a stream of particles called photons.
6.One of the most important wave-like behaviors of light is reflection. It is reflected light that we see with our eyes. How light reflects off objects affects the colors we see as well.
7.Electromagnetic waves are a form of energy waves that have both an electric and magnetic field
Wow those are some great facts. Shadows can be lots of fun to play with. Do you know how you can create a shadow?
ReplyDeleteA shadow is created when there is light and somthing blocks the light,underneath the object that is blocking the light is a shadow!!!!
