Laboratory Activity # 7 Quarter 2 Packet 3
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.
