1. Light and the electron

2. Speed of light (c) Light travels at 186,000 mi/s 3.0 x 108 m/s
c = 3.0 x 108 m/s

3. Wavelength (λ)
Distance between adjacent peaks in a wave. Measured in meters.

4. Frequency (υ) Number of peaks which pass a point per second.
υ = 1/s (Hz)

6. Putting it together
c = λυ
3.0 x 108 m/s = λυ

7. Photoelectric effect

8. Max Planck E = hυ E = energy υ = ?
h (Planck’s constant) = x 10–34 J · s
c = λυ

9. Electromagetic radiation (light)
To microwave

10. Infrared sensing organ or “pit”
Nostril

11. Back to EM

12. Microwave oven
