Wavelength (l) and Frequency (n) Relationships c=ln ‚ where l is wavelength in meters n is frequency in hertz‚ 1/s or s-1 c=3.0 x 108m/s (the speed of light in a vacuum) Typical question #1- What is the frequency of red light with a wavelength of 690.nm? (1m=109nm) First- l is wavelength in meters‚ so convert nm to meters 690.nm ( 1m )=6.90 x 10-7m 109nm Now we can rearrange the equation above and solve for frequency‚ since

The Green Light in The Great Gatsby The flashing light at the end of the dock across the water is first symbolically associated with Daisy. However‚ throughout the novel it gains new aspects and connotations‚ covering a full circle at the end of the novel. Throughout the novel the green light symbolizes various elements: Daisy’s love‚ money‚ renewal‚ death‚ and American Dream. The green light is introduced in chapter one for the first time: He stretched out his arms toward the dark water in a

Background Theory Photosynthesis: Plants require water from the soil‚ sunlight and carbon dioxide found in the atmosphere for growth and development. In the process of photosynthesis‚ carbon dioxide and water – in the presence of chlorophyll and light energy – are converted into sugar and oxygen‚ which is given off as a by-product. Generally‚ as sunlight increases in intensity‚ the rate of photosynthesis also increases [1]. This means greater food production within the plant. Many garden vegetables

Red from Green Maile Meloy’s short story “Red from Green” was first published in 2009. The short story is about the fifteen years old Sam Turner. Every year she goes on a float trip with her dad. This year Sam’s uncle and a client called Layton from her uncle’s law firm follow them on the trip. Layton compliments Sam’s white teeth and teaches her how to shoot with a gun he got with him on the trip. One night Sam gives Layton some massage because he has an old injury in his bag. When Sam’s dad and

Light that is visible to the human eye is a small portion of the electromagnetic spectrum which can vary in colour based on the wavelength of what is being seen at any particular time. This visible light has a primary function of causing electrons to become more active with higher energy rates. The colour that is seen revolves around the size of this portion which is noted as the wavelength. White light is a culmination of all colours which is the cause of it being the brightest. Furthermore‚ when

AP Lab #5 Plant Pigments/Photosynthesis I. Identifying the Effects of Different Variables of Light and Carbon Dioxide on the Rate of Photosynthesis and Observing the Separation of Pigments Through Chromatography II. Introduction Plants have a variety of pigments‚ all of which absorb a different color of light. The three main pigments are chlorophyll a‚ chlorophyll b and carotenoids. Chlorophyll a is the primary plant pigment that absorbs red and blue light‚ which ultimately appears green to the human eye

many variables that could affect the rate of photosynthesis and the net consumption of carbon dioxide. In this experiment‚ the effects of how the intensity of light energy affected photosynthesis were observed. Two pieces of elodea was placed into separate beakers and one of the beakers was placed under a bulb of lower intensity and the other beaker being placed under a higher intensity bulb. The results showed that the beaker under the higher intensity light energy had a higher consumption of carbon

out how light intensity can affect the rate of photosynthesis. Hypothesis I think that the further away the light source is the smaller the rate of photosynthesis is. This is because there is a further distance for the light to each the plant in order for it to photosynthesise. Although the closer the light source is‚ the more photosynthesis‚ the light source could also kill or damage the Elodea (type of pondweed) because it could become too hot and denature its cells. But because light intensity
