Effects of light 00:00:01
Reflection 00:00:11
Reflection happens when light hits an object and bounces back. 00:00:14
When light hits a smooth surface, the rays of light reflect in the same direction. 00:00:24
When it hits a raw surface, the rays of light will fluctuate in different directions. 00:00:31
Refraction 00:00:41
Refraction happens when light changes speed and direction as it passes from one substance to another. 00:00:42
The substance through which light travels is called medium. 00:00:52
Some mediums cause for more refraction than others. 00:00:58
For example, water slows the speed of light more than air does. 00:01:05
Lenses are pieces of curved glass or plastic that refract light. 00:01:12
Lenses can make objects look bigger or smaller depending on the shape of the lens 00:01:20
and on the way they refract light. 00:01:27
Characteristics of light 00:01:32
Light have seven colors, like the rainbow. 00:01:34
Red, orange, yellow, green, blue, indigo and violet. 00:01:40
