Light and Sound
light!
- light carries energy and travels as a wave
- light travels at 300000000 m/s or 300000 km/s
- light waves travel in straight lines
- light travels at 300000000 m/s or 300000 km/s
- laterally inverted - the image is reversed from left to right
- ray of incidence
- ray of reflection
- ray of incidence
- when the ray moves from a less dense medium to a more dense medium the light ray bends towards the normal
- when the ray moves from a less dense medium to a more dense medium the light ray bends away from the normal
- when light rays pass through a glass lens they are reflected. this means that they change their direction. a convex lense is fat in the middle. it brings the rays of light closer together. the rays of light are converging. the rays meet at a point which is called the focus. A concave lens is thin in the middle. it makes the rays of light spread out. The rays of light are diverging
