Red Orange Yellow Mixtures Of Pigments Color
582 wordsThe color wheel taught to most people today is the twelve-hue color circle developed by the Swiss color scientist, Johannes Itten. This color wheel is based on three mixtures of pigments, or a triad mixture, with red, yellow, and blue as the primary triad. All hues are formed from mixtures of equal or unequal amounts of primaries. Equal mixtures of two primaries result in the secondary hues and form the triad of green, orange, and violet. In this color wheel, six intermediate hues are created by...

Blue Light Significant Difference
1,039 wordsThe Effects of Various Wavelengths on Photosynthetic Rate Photosynthesis is the process by which autotrophic organisms convert light energy to chemical energy in the form of glucose [ 1 ]. Without this process life on earth would be very different because every organism directly or indirectly depends on photosynthesis. Because plants are at the bottom of the food chain they must create their own energy; this is done through photosynthesis. Various pigments located through out the leaves and stem...

Claude Monet Industrial Revolution
1,995 words"The Impressionists were subjective painters, who looked at nature in their own individual ways. The results were, hardly surprisingly, very different, when we consider the divergent styles of say Monet, Degas, Renoir, Gauguin, and Seurat. Perhaps the greatest achievement of Impressionism was to capture the effect of real sunlight on canvas. It is possibly this that made their pictures the most popular, and the most expensive, of the 20 th century. " Impressionism began in the late 1800 s in Fra...

Carbon Dioxide Hydrogen Ions
1,424 wordsPhotosynthesis is the process by which organisms that contain the pigment chlorophyll convert light energy into chemical energy which can be stored in the molecular bonds of organic molecules. Photosynthesis powers almost all trophic chains and food webs on the Earth. The net process of photosynthesis is described by the following equation: 6 CO 2 + 6 H 2 O + Light Energy = C 6 H 12 O 6 + 6 O 2 This equation simply means that carbon dioxide from the air and water combine in the presence of sunli...

Although defective color vision may be acquired as a result of another eye disorder, the vast majority of color blind cases are hereditary present at birth. A form of color blindness is present to some degree in about 12 per cent of males, and about 0. 5 per cent of females may be affected. Problems in distinguish...

Infrared Light Blue Green
344 wordsThe Basics. Sunlight plays a much larger role in our sustenance than we may expect: all the food we eat and all the fossil fuel we use is a product of photosynthesis, which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms, ranging from plants to bacteria (Figure 1). The best known form of photosynthesis is the one carried out by higher plants and algae, as well as by cyano...

H 2 O Carbon Dioxide
854 wordsColours Chloroplasts contain several different pigments the majority of which are chlorophyll a and chlorophyll b. Both of these types of chlorophyll absorb similar wavelengths of light, but chlorophyll a absorbs a slightly higher wavelength than chlorophyll b. Neither chlorophyll absorbs much light in the green region of the spectrum thus making it appear green. This can be plotted onto a graph (fig 1. 1). This graph is called the Absorption Spectrum. The Absorption Spectrum is very similar in ...
