Light bends in several(predicate) ways according to where the frolicsome is directed and what obstacles are in the way.
First of whole you need a light source. This could be the sun, a light bulb, a candle, a fire or any other type of luminous object. In this persona we are sack to use a ray encase (light bulb). We provide also use a cover that plainly lets one small ray through, so that we can envision what it does more quickly.
Reflection
If you business enterprise up the light ray in front of the mirror so it is at 90° the light testament not seem to go anywhere. This happens because first of all you draw a line of normal. This is a line that is 90° from the mirrors face. Then the light bounces back to where the light has come from. in any case if you shine the light at 45° on the remaining of the line of normal, hence the light bouncing aside will be 45° on the right of the line of normal. The line from the light source is called the line of incidence and the line that has bounced off is called the light of reflection. Also the original tend is called the line of incidence, where the angle of the light bounced off is called the angle of reflection.
Refraction
When you put a codswallop over block in the path of the light at 90° then nothing will seem to happen.
You will serious see it coming out the other end at a straight line. However if you put the light at 45° from the applesauce blocks front, then you will see it will turn into a bit of an s shape. This is because of TAGAGA. First draw a line of normal (at 90° from the glass block and where the light meets the block). T=towards A= place G=glass A=Away G=glass A=Air. This basically means that when light is going from cinch to glass it will slow down and bend towards the normal. When it is going from glass to air it will travel away from the normal. This is because glass is denser than air. Like imagine if you were threadning on the beach and then ran into the sea. The sea/water is denser so you are forced to run slower. When you shine light it goes...If you want to get a safe essay, order it on our website: Ordercustompaper.com
