Download file to see previous pages I used five different colors in the experiment. According to Timmermans, (2010) different colors of light have a significant effect on growth of plants, where the amount of energy obtained is different. However, it depends on other conditions, such as temperature, light intensity among others.
In this experiment, the researcher has four variables in place. They include independent variables (photosynthesis rate), dependent (effect of wavelength) and factors that are in control and those that were not in control. Control favors included number of leaflets, volume of NaHCO3, concentration of NaHCO3, size of disc used and power of the light that was used. On the other hand, uncontrolled factors were the room temperature that the experiment was carried in. The Hedera Helix discs (leaflets) in our experiment responded differently to different colors of light.
The hypothesis of the study is that the rate of photosynthesis varies in different colors of light. The blue color was expected to show the highest rate and yellow color the least effect to the rate of photosynthesis.
The requirements for carrying out this experiment successfully include a syringe and beaker/containers. Others incldued leaves (the Hedera Helix discs (leaflets)), holes cutter, NaHCO3 and source of light (colored light bulb).
I set up the five sources of colored light in an enclosed system and allowed it to warm up so as to attain equilibrium. I left the Hedera Helix Plant exposed to different light colors for 1.5 hours (90 minutes) using an analog-digital clocks to record the time elapses. This ensured that all the leaves were exposed to light equally. Using the prepared leaves, I prepared the NaHCO3 solution from 0.60g of sodium bicarbonate by diluting it with 300ml of distilled water in a 500ml beaker and added I added one drop of soap. I stirred the mixture gently ensuring that it does not form froth.
First I cut small holes into the leaves to obtain numerous ...Download file to see next pagesRead More

Ultraviolet light

...?Ultraviolet Light The purpose of this paper is to provide a brief discussion on the topic of ultraviolet light. The format that this paper will utilize is to first address some natural sources of UV light followed by a discussion of black light. After this point a discussion on the benefits and possible drawbacks of UV light. UV light is a source of electromagnetic radiation that is not part of the visible spectrum. Even though this light is not visible its effects can be felt by humans through the process of sunburns. The wavelength of UV light is ultimately shorter than that of light...

Light experiment

...? Molecular and cellular basis of life Molecular and cellular basis of life: Scenedesmus Molecular and cellular life science simply focuses on understanding the molecular levels in the functioning of a cell. This encompasses physical, chemical and biological computation of scientific principles. Physical aspects deal with requirements such as light, moisture and temperature. The chemical aspect entails properties of pH levels, and mineral composition while biological involves the relation to other biological aspects such as animals and plants within the same habitat. Introduction This project involves the study of Scenedesmus growth conditions. Scenedesmus refers to genus of the colonial green algae, with cell...

Measure and Light

...?The Gothic Cathedral, Otto von Simson, 1956, Chapter 2 , Measure and Light Introduction When someone enters a Gothic cathedral the things which immediately strike them are the vastness and symmetry of the solids materials and the ways in which these interact with the play of light , especially if the building is seen at different times of day and the shadows climb and fall, revealing and concealing as they travel. In the preface to this work von Simson describes the mediaeval period when Gothic cathedrals were sent soaring into the heavens as ‘an epoch of faith’ and the buildings as a physical expression of that faith. Chapter Two The chapter begins with a comparison with music. This can be enjoyed at...

Light Microscopy

...Swarnambika S Academia Research Light Microscopy October 9, 2007 Light Microscopy Microscopes that use visible light as a source of illumination are called light microscopes. Today’s light microscopes are compound microscopes. They provide greater magnification and are much easier to use. Compound microscopes have two lenses, an objective lens and an ocular lens, both of which are corrected lenses (several individual lenses bonded together) that compensate for the aberrations inherent in ordinary lenses (James & Tanke, 1991). Uncorrected aberrations produce images that are surrounded by colored rings (chromatic aberration), and not all parts of the field of observation are simultaneously in focus (spherical aberration). Parts... of...

Ultraviolet Light

...Ultraviolet Light Ultraviolet (UV) light was first discovered in 1801 by, a German physicist, Johann W. Ritter. In the electromagnet field, this light lies between X rays and violet light. The wavelength ranges between 100 nanometers and 400 nanometers. UV light is naturally produced by the sun. Other sources include black lights, tanning booths, germicidal lamps, laser sources, fluorescent lamps and mercury vapor lamps. The UV light forms part of the invisible light in the electromagnet spectrum. However, some insects and birds are capable of perceiving this form of light. This spectrum...

UV Light

...Patterns in Nature Ultraviolet light commonly referred to as UV light is a form of an electromagnetic radiation apparently not visible to the human eye, having a shorter wavelength as compared to the light visible to humans. This light is comparatively stronger carrying more energy than normal light and can rupture the chemical bond in atoms or molecules eventually damaging the initial chemistry of the substance that has been exposed to it. A feature of UV light is that it causes fluorescence causing certain materials to radiate visible light. Sunlight also contains UV light and is a good source of...

Ultraviolet light

...Ultraviolet Light In terms of wavelengths, UV light has shorter than visible light wavelengths. Visibility of light differs from one entity to another and therefore living organisms have different capabilities in seeing various types of light. For some organisms such as insects, bumblebees for an instance, can see UV light, unlike humans. The sun is considered to be the primary source of the full spectrum of UV radiation. There are three kinds of UV-rays/radiations namely UV-A, UV-B, and UV-C. With reference to wavelengths and effect, UV-C radiation is the most harmful and absorbed within the Earth’s atmosphere. Additionally, UV-B is...

Light in the Cave

...Light in the Cave It was two summers ago. The sun was warm on my face and the day was bright. The view of rocks below reminded me of the long way down if I fall. There was no firm guardrail and the only thing I had to rely on was my footedness, and I was not so sure of it. My legs began to shake and cold sweat broke out. Suddenly the world started to blur and my thoughts began to take over. I was not just scared but terrified of heights. But what happened on that day made me forget all my fears and made it the most memorable experience. My fear of heights overtook my love of nature. Hiking to me was a crazy adventure. My friends were so excited about exploring a cave they had driven past a few days ago. But they...

Color and Light

...Color and Light Color is an aspect caused by different qualities of light being emitted by an object and is then defined in terms of the observer’s perception. For an individual to see any color, light must be present. Therefore, when light shines on any object, some colors bounces off the object and others are absorbed by the object. Hence, the eyes only see the colors that are bounced off or reflected by the object. Scientists have discovered that sun rays contain all the colors of the rainbow when combined. As such, whenever the white light strikes a white object, it appears white in the eyes of human beings since white objects absorb no colors and...
