3. What is the sun? Light Sources 100
The electromagnetic energy from this source makes life on Earth possible for us
What is the sun?

4. What is artificial light?
Light Sources 200
Incandescent, fluorescent, LED and neon bulbs are common forms of this type of light
What is artificial light?

5. What is natural light? Light Sources 300
The sun, stars, and the Northern lights are forms of this type of light.
What is natural light?

6. What is bioluminescence?
Light Sources 400
Fireflies are a good example of this type of light, which is created by living organisms
What is bioluminescence?

7. What is reflect the sun’s light?
Light Sources 500
Although it appears to be a light source, the moon does not create light. It only does this…
What is reflect the sun’s light?

8. What is the peak or crest?
The Wave 100
The top of a wave is known as this.
What is the peak or crest?

9. What is the wavelength or frequency?
The distance from the crest of one wave to the crest of the next wave is known as this.
What is the wavelength or frequency?

10. Light can pass through this, where there is no matter.
The Wave 300
Light can pass through this, where there is no matter.
What is a vacuum?

11. The unit used to measure frequency of a wave is called this.
The Wave 400
The unit used to measure frequency of a wave is called this.
What is the Hertz?

12. What are sound and water?
The Wave 500
From our past units of study, these things also travel in waves, even though they are not part of the electromagnetic spectrum.
What are sound and water?

13. Electromagnetic Spectrum 100
True or False…
All forms of energy on the electromagnetic spectrum are visible.
False

14. Electromagnetic Spectrum 200
These are the longest types of waves on the electromagnetic spectrum. We use them to communicate.
What are radio and TV waves?

15. Electromagnetic Spectrum 300
These waves have a slightly longer wavelength than the visible spectrum. We can sense them as heat.
What are infrared waves?

16. Electromagnetic Spectrum 400
True or False…
The shorter the wavelength on the electromagnetic spectrum, the more energy that type of wave has (and the more dangerous it is).
True

17. Electromagnetic Spectrum 500
Name three types of waves that have wavelengths shorter than those of the visible spectrum.
What are ultraviolet, x-rays, gamma and/or cosmic rays?

18. What are red, orange, yellow, green, blue, indigo and violet?
Visible Light 100
These are all 7 colors of the visible light spectrum, also known as the colors of the rainbow.
What are red, orange, yellow, green, blue, indigo and violet?

19. What is white light? Visible Light 200
All the colors of the rainbow can be seen when this color light is refracted through a prism.
What is white light?

20. What is green? Visible Light 300
The primary colors of light are red, green and blue. An object that reflects only green light will appear to be what color?
What is green?

21. A black sweater feels warmer than a white sweater because of this.
Visible Light 400
A black sweater feels warmer than a white sweater because of this.
Because black objects absorb all the colors of the visible spectrum and do not reflect as much light or heat.

22. Visible Light 500
Explain why a green object appears to be black when placed under a red filter.
Because the red filter only allows red light through. The green object only reflects green light, and absorbs red and blue light. So this object absorbs all the light it can and does not have any green light to reflect.

23. When light bounces off a surface, this is called…
Mirrors, Lenses & More 100
When light bounces off a surface, this is called…
What is reflection?

24. When light hits an object and slows down and bends, this is called…
Mirrors, Lenses & More 200
When light hits an object and slows down and bends, this is called…
What is refraction?

25. What is a prism? Mirrors, Lenses & More 300
This type of object separates white light into all the colors of the spectrum by refraction.
What is a prism?

26. What are concave (curve in) and convex (curve out)?
Mirrors, Lenses & More 400
Lenses can be used to make things appear larger or smaller to the viewer. Lenses that curve in are called _________ and lenses that curve out are called _________.
What are concave (curve in) and convex (curve out)?

27. Mirrors, Lenses & More 500
When light hits a mirror and is reflected, the angle it comes in at is called the angle of _______. The angle it is reflected at is called the angle of _________. With a flat mirror, these angles are always equal to each other.
Incidence –the angle the light comes in
Reflection – the angle the light is reflected at.
