| Visible Light Spectrum/ Soap Bubbles Lab Problem: How can a continuous colored light spectrum be observed in a lab? Procedure: 1) Pour 5mL of glycerine in a 250mL beaker 2) Pour 15mL of dish washing soap into the 250mL beaker 3) Pour 40mL of water into the 250mL beaker 4) Stir the solution well 5) Bend a paper clip to form a loop 6) Blow a large bubble on the loop and examine the colored spectrum on the surface of the bubble. Information: Electromagnetic spectrum: From least energy to greatest energy: Radio waves, microwaves, Infered light waves, visible light waves, ultra violet waves, X-Rays, gamma rays Safety Notes: 1) Wear Saftey Goggles 2) Do not blow bubble in class Conclusion: 1) Using C=wavelength x frequency,, determine the frequency of light with a wavelength of 400.00 nm. 2) Using C=wavelength x frequency, determine the frequency of red light if it has a wave length of 700.00nm. 3) List all of the important polyatomic ions with their oxidation numbers. |
