1. Electromagnetic Spectrum
Components of the Spectrum

2. Speed of light= 3.0 x 108 m/s
Speed of sound 340 m/s
Thus what

4. Wavelength
The distance from crest to crest of a wave.

5. Frequency
How often a wave occurs over a given period of time.

6. Let’s put them together

7. Formula you need to know
Wavelength x frequency = speed of light
λ*ν = c
c= speed of light
λ = wavelength
ν = frequency

8. How do those terms fit in the spectrum?
High wavelength
Low wavelength
Low frequency
High frequency

9. Wave characteristics affect how much energy released
Long wavelength
short wavelength
Low frequency
High frequency
Low energy
High energy

10. Components of Electromagnetic Spectrum

11. Gamma Rays

12. X-Rays

13. Ultraviolet Light

14. Visible light is a small part
High energy
Low energy

15. Infrared

16. Microwaves

17. Radio Waves

18. When do we see the light?
When atoms gain energy they jump up an energy level = unstable
To get back to stable it releases the energy to fall back down
This energy released is light
Depending on the atom = different wavelength of light
