s3398334 – Paulo Balino Colour Symbolism RED is the color next to orange at the end of the visible spectrum. The wavelength of red light is approximately 620-740 nm on the electromagnetic spectrum. History of RED Inside cave 13B at Pinnacle Point‚ an archeological site found on the coast of South Africa‚ paleoanthropologist in 2000 found evidence that between 170‚000 and 40‚000 years ago‚ Late Stone Age people were scraping and grinding ochre‚ a clay colored red by iron oxide‚ probably with the intention

alcohol on an index card within the enclosure. The same size drop was used each time the step was repeated. The time it takes for the drop to evaporate without the LED present was recorded. The dark spot on the card caused by the alcohol was no longer visible. A flashlight was used to help with the observance of the dark spot. The evaporation time was recorded. The same procedure was repeated for the different colored LEDs over the alcohol drop. The current through each LED and the distance from the LED

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 data was graphed it clearly showed the higher rate of red light absorption over green light. These results along with previous research indicate the importance of red light in photosynthesis and the minor role

Introduction It is common knowledge that plants need light to grow and develop. This is done by the conversion of light energy into usable sugars during photosynthesis. Light absorbing molecules‚ known as pigments‚ absorb only specific wavelengths of visible light‚ mostly blue and red wavelengths (1). Whatever wavelength isn’t absorbed is reflected and the reflection is the color of plant we see. Plants also respond to wavelengths of light in non-photosynthetic related responses allowing them to adjust

plays a major role in setting up a particular mood or state of mind. Color does affect one’s feelings‚ moods‚ and emotions. Colors are certain wavelengths of electro-magnetic energy seen through our eyes. The color we see is the part of the visible spectrum that is reflected back by a certain object. We know that when all colors join the result is white light. Therefore working with White Light brings about completeness‚ oneness‚ union of all complementary parts. Colors affect us in different

between the photons (or wavelengths) you get what is commonly known as a visible light wave. Light is very common in the Universe. Light is so common that everything on Earth has evolved to us life to its advantage to survive. If you were to take a prism and put light to it‚ it can slow light down by a fraction by revealing its much more colourful side. This is commonly known as the visible light spectrum. On one end of the spectrum you have red and on the other you have Violet. Red is red because its

you order for the panels in this project? What wavelengths of light will be absorbed by theses filters? So you think this proposal will be effective in killing the duckweed? Primary photosynthesis occurs in the red and blue regions of the visible light spectrum. By inhibiting light passage for wavelengths of 700-635nm and 490-450nm‚ most photosynthesis would become inefficient. This would most likely kill the pest as well as most other primary photosynthetic life.

Color sells products. It is a powerful marketing tool that significantly influences consumer purchases‚ so much so that it accounts for 85% of the reason why someone decides to purchase a product (Hemphill 275). Marketers must understand the psychology of color in order to employ it effectively. Colors possess the ability to take an action and influence human behavior and emotion‚ and when properly used can be a vital tool in a successful marketing scheme.
