Reflection & Refraction

 

Reflection occurs when light bounces off objects.  How much reflection depends upon how even the surface is.  If the surface is rough, the light scatters.  If the surface is smooth and flat, the light will bounce off it at equal angles.  That is why a flat mirror reflects a good likeness of the object being reflected.

Look at the diagrams below.  Notice the angles at which the rays of light strike the surfaces.

Light Reflection

Refraction occurs because light bends.  A lens is a piece of transparent material.  It is usually made of glass and has at least one curved surface. Look at the convex and concave lenses below.

Convex & Concave Lenses

The curved surface/surfaces of a lens bends the light.  Notice the paths of light of the convex and concave lenses shown below.

100 WC Week 9

I came inside from being in the pool, wet and cold. ” A piece of chocolate” I say. It smells so good. I check to see if  l am alone. No one’s coming so I eat it. Once it went down it started  to melt in my throat, “yummy” I said.  I wanted more and more so I started to search the kitchen until I found more.  Then I saw mum coming. I stopped searching and got off the table, jumped off chair and landed on my feet. Mum came in to the kitchen with a plate of brownies and l was able to eat somemore.”Yummy, yum, yummy, yum, yummy.”

100 word challenge(Grandparent are important becaues)

Grandparents are important because they know more than our parents, they make me laugh, they are always on my side,  they are happy to see me, they are grumpy sometimes, they know about the olden days, they fart a lot and  they sleep on the couch while the t.v is on. They make yummy biscuits and cakes, they brush your hair. Also you wouldn’t be here if your grandparents  where never here becuaes  your grandparents create your parents but with out your grandparents your parents wouldn’t be here and that means you wouldn’t be here. That’s why Grandparents are so important.
