What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived

ummary: Did you ever think that how the street lights automatically turn ON in the night and turn OFF automatically at morning? Is there any person who comes to ON/OFF these lights? The following circuit that described below which perform this job automatically. This circuit employed the output from an uncomplicated light/dark activated circuit and oblige a relay in its output which can be further attached to switch ON/OFF a street light and electrical application in a household also. Many of the

Photosynthesis is the process by which light energy is used to convert inorganic compounds into organic substances with the subsequent release. There are many factors which can have an effect on the process of photosynthesis; in this laboratory experiment‚ the focus lies on carbon dioxide (CO2) availably and its effect on photosynthesis. By understanding the component that affect the rate of photosynthesis‚ one can do work to try and increase the rate of photosynthesis. The purpose of this laboratory

If you are interested in learning the benefits of high intensity interval training‚ your concern with personal fitness is likely greater than the average person’s. High intensity interval training at its most effective level is not for the average Jane or Joe. HIIT‚ as it is also referred to‚ can make even a professional athlete weep. But the results are worth it. High intensity interval training has the advantage of requiring much less time to produce great results. It is designed to achieve rapid

Scattering of Light | The scattering of light is an important observation in our daily life. The way light scatters off molecules in the atmosphere explains why the sky is blue and why the sun looks red at sunrise and sunset. This is because of the scattering of light. | | | Tyndall Effect A beam of light or laser‚ invisible in clear air or pure water‚ will trace a visible path through colloidal particles. This is known as the Tyndall effect after its discoverer‚ the 19th-century British

Lights‚ Camera‚ Action. Light it up. As the popular Soca song goes‚ ‘Let me see you light up the Air’. Or Vybz Kartel’s song says ‘Light the Weed’. All focused around the presence of light. We cannot see without light‚ so in this regard‚ light illuminates our path. For this reason we ensure that our surroundings are fitted with lightbulbs. We cannot function in school or work or in life if there isn’t some measure of light. I’m here to enlighten you about the choice that you will face when purchasing

Essay 1: Light and Color The fascinating properties of light are not all detectable to humans‚ because our reference is mostly limited to what we can see. In order to determine the atomic/molecular composition of a fluid or gas‚ one must consult an emission and absorption spectrum. The properties of this spectrum include also waves‚ which can be any length‚ and define the spectrum of electromagnetic radiation. Ranging from gamma rays to radio waves‚ an electromagnetic spectrum includes each

plant. Plants and trees cover about thirty percent of the planet’s surface‚ as stated in NASA’s Earth Observatory division. They use a process called photosynthesis‚ which allows plants to take energy from the Sun and later using it as food‚ as well as producing oxygen through the process of respiration. So how does it happen? The process of photosynthesis occurs as follows. First‚ the plant uses the sunlight and the green color in their leaves to make sugar from carbon dioxide‚ or CO2‚ which is in the

Having observed these problems being encountered‚ this project will be developed to bring about the automation of the switching of lighting system using light depending resistor (LDR). The project is an electronic switch that is controlled (turned on and off) by the amount of light shining on the LDR. When light strikes the LDR‚ the switch opens (turns off); when the LDR is in darkness‚ the switch
