knowledge of one fourth wavelength to create our own demonstration. It does not only have to be done using wind‚ but can also be demonstrated using tuning forks. If the frequency of the tuning forks is known‚ then v=f(wavelength) can find you the length of your air column. Using a tuning fork of frequency 512 c/s‚ and the speed of sound is 332+0.6T m/s‚ temperature being‚ 22 degrees‚ substitute into the formula. Calculate 1/4 wavelength V=f(wavelength) wavelength=V/f

Observing Flames and Specs through a Spectroscope By: Seif Alkhouri Cristian Plancia-Mata Charlotte Maxwell Suryansh Kumar Evan Hatton J. Immel Ph.D Introduction Spectroscopy is the study of the interaction between matter and radiated energy. English philosopher Roger Bacon(1214-1294) was the first person to recognize that if sunlight passes through water it splits into colors. Around four centuries ago‚ Isaac Newton originated the title “spectrum” to label the shade of rainbows put

speed light using a microwave oven; but I wanted to know if such thing could be possible. Speed light can be measure in such commons things as a microwave oven‚ a television‚ a radio and all the things that use electromagnetic waves‚ although the wavelength might vary. My hypothesis was that the eggs will have give a more accurate result to the speed light number published which is 299’792’458 m/s; I was wrong‚ according to my result the buttered bread is the best food to measure speed light‚ using

Figure 4: Malvidin present in grapes (http://www.friedli.com/herbs/phytochem/anthocyanins.gif) The Visible Spectrum The mixture of chlorophyll found in spinach absorbs many wavelengths of the visible light. The absorbance peaks ranges 400 – 500nm is the blue range and 600 -700 nm the yellow- red range. The two principles of this light absorption stated (Practical Skills in Chemistry‚ 2011) are: 1) the absorption of light is

collected from the monastery of Saint Anthony in Egypt. The origins of the monastery are due to the 4th century AD. FTIR–ATR spectra were collected on a Perkin Elmer spectrometer 400 equipped with an ATR detector (attenuated total reflectance) in the wavelength range of 4000–650 cm–1‚ at a spectral resolution of 4 cm–1 over 32 scans. In attenuated total reflectance (ATR) spectroscopy‚ the sample is placed in contact with a special crystal (e.g.‚ zinc selenide‚ ZnSe). Figure 6 shows FTIR–ATR spectrum of
