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

How do different economic systems affect quality of life? The mixed economy gets the best of both worlds. I believe that the planned economy is a last resort and a not smart idea. My reasoning behind this is the fact that the government should not have full control over the economy‚ but I believe the citizens should have a voice‚ and that voice should be recognized. When the economy is a mixed‚ citizens have a voice‚ but so does the government. In my opinion‚ I think that the mixed economy

radiation affect the growth of seeds? If‚ plant seeds are exposed to microwave radiation‚ then the seeds will grow less than how a seed is usually grown. The independent variable was the amount of microwave radiation the seeds receive. The dependent variable was the growth of the plant seeds. Control variables were the amount of water (30 mL at a time)‚ the amount of light (11 hours each day)‚ and the amount of seeds. The control group was the non-microwaved seeds. The experimental group was how long

How does a Lens Refract Light? Different Lenses refract light in different ways. First‚ we will look at a double convex lens. Several light rays will approach the convex lens in a parallel manner. After they approach the lens‚ each ray will refract towards the normal. The light is passing from an optical less dense medium (Air) into a more dense medium (such as plastic or glass) at this boundary. Since the light rays are passing the boundary from a less dense medium in which light travels fast (optically

of fertilizers on plant growth | | | Year 11 Biology Year 11 Biology Abstract An investigation was carried out to compare the effect between inorganic and organic fertilizers on plant growth. Tomato seedlings were used‚ which were divided into 3 groups - the inorganic fertilizer group‚ the organic fertilizer group and the control group. Besides using different fertilizers‚ all of the seedlings were planted in the same condition. The result has shown that the plants using organic fertilizer

Question: How can different masses of salt affect the percentage of transmitted light? Variables – Independent – • Mass of salt‚ the salt added into the distilled water in grams (0.1‚ 0.5‚ 0.75‚ 1‚ 1.5) Dependent – • Percentage of transmitted light through the solution using 5 different mass of salt and a constant availability of 2g of sugar as source of food. (there are 5 trails for each conical flask representing 5 different salt masses) Controlled – What is being Controlled? How will

The Effect of Watering on the Plant Growth 1. Problem/Question: Sarah observes the small garden in their house. She ask her mother why are the plants needed water but it has fertilized already. Their plants aren’t grow . So she decided to experiment on what is the effect of watering on plant growth. 2. Observation/Research: She water them every day‚ they have good soil‚ and they’re in the shade. 3. Formulate a Hypothesis: Sarah think plants will grow better if they’re in the sun

Introduction: Photosynthesis can be defined as light energy being converted into chemical energy‚ which is a very important process for plants and other organisms. Light can be described in terms of light quantity and light quality. Both of these have an affect on photosynthesis. The more light a plant absorbs the more the plant is able to photosynthesize. This light is absorbed though pigments which have specific interactions with certain light waves (colors). The goal of my first experiment

How do volcanoes affect people and environments? Each year there are approximately 50-70 volcanoes that erupt. Those volcanoes affect the people and environments in many different ways. According to the article “How many active volcanoes are there? (Tom Simkin and Lee Siebert) there are about 20 volcanoes erupting right now. Volcanoes can affect people and environments in many uncounted ways. One important thing that can affect the environment is that the volcanic soils help the environment in
