Presentation Transcript


1. Electromagnetic Spectrum Foldable

2. To begin…. Take a blank piece of unlined paper Fold it like a hotdog with a flap of about 1 inch on the top Divide the flap into twelve equal sections, about one inch each You can fold the paper, instead of measure

3. On the flap… Make lines on each measured section On the flap, write the wavelengths in m 10-16, 10-14, 10-12, 10-10…………until you run out of lines

4. Open the flap…. On the same lines, but hidden by the flap Write frequencies 1024, 1022, 1020, 1018……..until you run out of lines The lines should have frequency and wavelengths that are equal on them 10-16s-1* 1024m= 3.0*108m/s

5. On the leftover space inside… Put your formulas E = h(m) E: energy (Joules) h: 6.626 x 10-34 Joules/Hz - m : frequency (Hz or 1/second) ?(m) = c ? : wavelength (meters or centimeters) - m : frequency (Hz or 1/second) c = 3.0 x 108 m/s or 3.0 x 1010 cm/s

6. Also on the inside…. Put the wavelengths for visible light Red- 650nm Orange- 590nm Yellow- 570nm Green- 510nm Blue- 475nm Indigo- 445nm Violet- 400nm

7. On the outside of the flap… Write the types of electromagnetic radiation with their corresponding wavelengths Gamma- typically < 10-12 m X-ray- 10-9m -10-12 m Ultraviolet- 400x 10-9m - 10-9m Visible- 750 – 400x10 -9m Infrared-10-3m – 750x10 -9m Microwaves- 187 - 10-3m Radiowaves- >187m
