| Physics: Light | Light is a form of energy and can be converted into other energy forms. Solar Panels -Electricity Photosynthesis - Chemical |
| Light travels in straight lines. TO show this, set up an experiment like so. | White light contains colours we can see under certain conditions. White light is made up of different colours called the spectrum of light. An example of this is a rainbow. The sun shines through the raindrops. |
| Dispersion: the breaking up of white light into its spectrum colours. (spré) | Because of the periscope there is a double reflection so you will be able to see over the obstacle. |
| If you place a pencil in a glass of water, it looks like if it is bent where it enters the water. This is because of REFRACTION. | * Refraction is the bending of light as it passes from one transparent material to another. * (refraction = athraonadh) |
| Convex lens ; When the light falls on a convex lens it refracts and comes together at a point called the focal point. | A prism uses refraction to form a spectrum of coloured light! Thats all for Light, yay! |
