All You Ever Wanted to Know About Light
3
Watch and Learn…. Click the “TV”
4
COLOR White light is made up of all the colors of the rainbow put together.
5
See How a Prism Works Click the “TV”
6
When white light rays hit something, some colors in the white light are absorbed and some are reflected. The color that is being reflected is the color of the object. All other colors are being absorbed.
7
For Example: Blue is being reflected all other colors are being absorbed Red is being reflected all other colors are being absorbed
8
Something that is white is reflecting off all the colors to the eye, so it appears white. Something that is black is absorbing all the colors, so it appears to be black. Black is considered the absence of all colors.
9
Since darker colored materials absorb more light rays---darker colored materials are usually hotter
10
TRAVEL Light rays travel in a straight line unless something causes it to change directions
11
If light rays travel through something denser (thicker) than air, the light rays bend. This is called REFRACTION!
12
Refraction is the bending of light rays DRAW these examples and add the refracted rays: Empty Glass: Ray is bent a little since it must go through the glass Glass of Water: Ray is bent a little more since it must go through both the glass and the water Glass of Oil: Ray bent a lot more since it must go through the glass and the oil is more dense
13
Examples of things that we use to refract light: Hand lens Eye glasses Microscopes Telescopes
14
REFLECTION is when light rays bounce off an object!!
15
Examples of things we use to reflect light: Mirror Shiny Metal
