1. Electromagnetic Spectrum

2. Multiplying & Dividing of Integers
How many kinds of “waves” are there in this picture?
Multiplying & Dividing of Integers

3. We know what waves are

4. We know that the sun sends all kinds of waves to the earth

5. We know these energy waves are divided into categories based on wave lengths; Shortest to Longest

6. We know that the 3 categories are: Ultraviolet Light Infrared

7. Our focus will be on the second category:
Light

8. Light Because these waves are the ONLY wave that can be seen
By humans. Bees see colour in ultraviolet light.

10. Light makes up only 3% of the entire spectrum

11. Would that fit the definition?
A disturbance that travels through a medium?

12. If the spectrum stretched from the East Coast to the West Coast
The light waves that we can actually see would fit in around Toronto and be the size of a nickel.

13. As discussed in the video, wave lengths vary in light waves
Red = slowest
Moving to
Blue = fastest

14. When we talk about the speed of osculating waves
We are talking about HUNDREDS of TRILLIONS of times per second!

15. It is important to note that:
Whoa Dude
It is important to note that:
Waves are measured in “wave lengths”
More on that later
Righteous!

16. How to we see light?

17. Our eyes are designed to acknowledge the frequencies of visible light

18. Remember how many times the light waves osculated in the visual light?

19. Good Question
HUNDREDS of TRILLIONS

20. Our eye can interpret the speed of these wave lengths

21. When you look at a banana what color do you see?

22. The sun releases waves of energy

23. WHY?

24. The categories are divided based on the length of waves; Shortest to Longest

26. Can we bend Light?

27. How?

29. Even longer waves = Radio & Microwaves

31. Ultraviolet

32. Some that evade the naked eye
Some we can see
Some that evade the naked eye
