Effects of light

2
00:00:11,890 --> 00:00:14,669
Reflection

3
00:00:14,669 --> 00:00:22,870
Reflection happens when light hits an object and bounces back.

4
00:00:24,190 --> 00:00:31,329
When light hits a smooth surface, the rays of light reflect in the same direction.

5
00:00:31,329 --> 00:00:40,090
When it hits a raw surface, the rays of light will fluctuate in different directions.

6
00:00:41,570 --> 00:00:42,210
Refraction

7
00:00:42,210 --> 00:00:52,630
Refraction happens when light changes speed and direction as it passes from one substance to another.

8
00:00:52,630 --> 00:00:58,770
The substance through which light travels is called medium.

9
00:00:58,770 --> 00:01:04,370
Some mediums cause for more refraction than others.

10
00:01:05,790 --> 00:01:11,129
For example, water slows the speed of light more than air does.

11
00:01:12,530 --> 00:01:18,189
Lenses are pieces of curved glass or plastic that refract light.

12
00:01:20,409 --> 00:01:27,930
Lenses can make objects look bigger or smaller depending on the shape of the lens

13
00:01:27,930 --> 00:01:30,950
and on the way they refract light.

14
00:01:32,829 --> 00:01:34,450
Characteristics of light

15
00:01:34,450 --> 00:01:40,010
Light have seven colors, like the rainbow.

16
00:01:40,569 --> 00:01:46,450
Red, orange, yellow, green, blue, indigo and violet.
