A Spectrophotometric Analysis of the Absorption of Green Light Versus Red Light Absorption in Spinach Leaves The goal of the experiment was to determine if green light had less ability to absorb than red light in spinach leaves. This was done by separating the photosynthetic pigments (chlorophyll a‚ chlorophyll b‚ carotene and xanthophylls) from one another using paper chromatography. The separated pigments were then analyzed for their absorption spectrum using a spectrographometer. When the

for this experiment‚ the study of the effects of different wavelengths on leaf pigments‚ if chlorophyll a absorbs blue-violet light‚ chlorophyll b absorbs blue light‚ carotene absorbs blue-green light‚ and xanthophyll absorbs blue light‚ then wavelengths of greatest absorption will be 400‚ 450‚ 500‚ and 450 respectively. Independent Variable: Wavelengths Dependent Variable: optimum wavelengths of light for absorption Standard Variable: method of measurement‚ what was measured Predictions:

The autism spectrum refers to a number of conditions that are linked together by similar characteristics and symptoms. There are a wide range of skills‚ symptoms and levels of impairments or disabilities that are associated with autism. Every person with autism will have an array of characteristics and they will differ from another person with autism. The symptoms are over a spectrum and people with autism may how some of the symptoms on the spectrum but not all of them. There three areas of difficulty

Radios and microwaves both use radiation from the electromagnetic spectrum Visible light can be split into a spectrum of colours .. from red through the rainbow colours to violet but visible light is just a small part of the whole electromagnetic spectrum All the different types of electromagnetic waves travel at the same speed through a vacum .. the waves can be orderd by wave length remebered that waves with the shortest wave lengths have the highest frequency and the most energy and the waves

The Figure 6-18 in my text book was an example of an electromagnetic spectrum‚ which is all wavelengths of light both seen and unseen (Trefil & Hazen‚ 2010). The display of the electromagnetic spectrum showed gamma rays‚ X-rays‚ ultraviolet light‚ infrared‚ visible light‚ microwave‚ radio waves‚ as well as a visible spectrum wavelength (Trefil & Hazen‚ 2010). The diagram shows at what frequency and wavelength each wave moves and what it allows us to see‚ hear‚ and feel with visible light

Describe your strongest dimension on the personality spectrum. My strongest dimension on the personality spectrum is coping with pressure. I always knew that I worked very well under pressure‚ because of past job I have worked‚ and the situations they placed me in. I always try to be an optimistic type of person viewing the glass as half full instead of half empty. As I see it‚ if a situation is bad‚ it could always go from bad to worse. One reason I excel at work is that I don’t sweat the small

Different political views are represented by the political spectrum. The spectrum shows that on the extreme left end is communist views and on the extreme left is dictatorship views and anywhere in between is liberal‚ conservative or a combination of both parties. In the left end views are that everyone is equal and has the right to have the same things as every other person whereas on the right side views are that the successful should be awarded. Political parties on the right and those on the

The Electromagnetic spectrum is just a name for the range of ALL possible frequencies of electromagnetic radiation. The "electromagnetic spectrum" of an object has a different meaning‚ and is instead the characteristic distribution of electromagnetic radiation emitted or absorbed by that particular object. The spectrum extends from below the low frequencies used for modern radio‚ to gamma radiation at the short-wavelength (or high-frequency) end‚ therefore covering wavelength for

Electro Magnetic Spectrum Fontana Chemistry period 3 December 3‚ 2012 James Clerk Maxwell discovered the electromagnetic spectrum in 1862. The electromagnetic spectrum is a map of all the types of light that can be identified. It classifies different types of light by wavelength to show how much energy the wave has. The more energy the wave has the shorter the wavelength and the less energy a waves has the longer the wavelength. Not all light is in the visible spectrum. There are many kinds

When will profits reported under variable and absorption costing differ? How can we reconcile the profits reported under the two approaches? Profits reported under variable and absorption costing will differ when inventory increases or decreases during the year. The difference involves the timing with which fixed manufacturing overhead becomes an expense. Under variable costing‚ fixed overhead is expensed immediately as it is incurred. Under absorption costing‚ fixed overhead is inventoried until
