The properties of light have been understood by physicists to be completely fundamental to our understanding of the universe, however defining these properties have proven difficult to elucidate. What is light? What is light composed of? Does light obey classical physics? These questions are important to answer when considering physical phenomena that involve light. One…
Properties The speed of light is measured through the equation: v = λ f. However, it turns out that when light is reflected off a surface its speed stays the same. This was first proven by Sir Isaac Newton. Under the assumption of perfectly elastic collision, the laws of reflection follow from the laws of…
Temperature Most seeds need a certain degree of warmth to germinate (sprout). Most plants have an optimal (best) range of temperature for growth. Higher: Plants have smaller leaves, thicker cuticles, and wilt is more likely to occur. Lower: Grow lower to the ground, have shorter life cycles, and dish-shaped leaves. Temperature affects moisture and nutrient…
– As the human population keeps increasing (it’s over 6 billion people right now), we keep requiring more and more energy. – Using too much energy places stress on our energy production systems and may cause blackouts when we need the energy the most. HOW DO WE USE ELECTRICITY? – In order to conserve (save)…
Everything in the universe is either matter or energy. We studied matter in the Chemistry unit; it is everything that we can touch, smell, taste, and see. Energy is the ability to do work and it comes in many different forms. Forms of energy include kinetic energy (energy of movement), light, heat, solar energy (from…
Light Reactions: – require chlorophyll and take place in thykaloid membranes – absorb light energy and transfer it to ADP and NADP+ – energy is transferred to carbohydrate molecules in the Calvin cycle Carbon Fixation: – incorporate molecules of CO2(g) into organic molecules, such as glucose – require energy from ATP and NADPH – takes…
The tools available to artists have increased and changed the ways we can create. In light of this, we have to find new ways to describe artwork. Earlier in the course we learned about the elements and principles of art and design. Now that we have had time to consider and use some of these…
