• Light wavelength effect on the photosynthetic rate of elodea.
Introduction: The rate of photosynthesis varies greatly with changes in wavelengths of light. Light's colour is determined by its wavelength of light, and thus it is possible to devise an experiment to determine which wavelengths of light are most productive for photosynthesis than others. In this experiment I use a plant called Elodea (pond weed). Elodea is native to North America and it is also widely used as aquarium vegetation. The basic structure of these plants are whirls of leaves...

• Anechoic Chamber - 2020 Words
------------------------------------------------- Anechoic chamber An anechoic chamber (an-echoic meaning non-echoing or echo-free) is a room designed to stop reflections of either sound or electromagnetic waves. They are also insulated from exterior sources of noise. The combination of both aspects means they simulate a quiet open-space of infinite dimension, which is useful when exterior influences would otherwise give false results. Anechoic chambers were originally used in the context...

• H.S. Level - Sound and Light Waves
Sounds are produced by the vibrations of material objects, and travel as a result of momentum transfer when air molecules collide. Our subjective impression' about the frequency of a sound is called pitch. High pitch has high vibration frequency, while low pitch has a low vibration frequency. A pure musical tone consists of a single pitch or frequency. However, most musical tones are "complex summations" of various pure frequencies - one characteristic frequency, called the fundamental, and...

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...

Abstract: The interferometer is the most accurate measuring device known to man. It was created by Albert A. Michelson. The operation of the interferometer described briefly is a light beam that is separated by a beam splitter. The two beams then travel equal distances at 90° of each other where they are reflected off two mirrors back through the beam splitter. They are then superimposed on to a screen. The screen will display an interference pattern of fringes. The...

What exactly is the electromagnetic spectrum? Is a continuous range of wavelengths, which includes gamma rays, ultraviolet waves and other forms of electromagnetic radiation. How does the issue of scarcity and interference relate to the electromagnetic spectrum?

Standing wave Standing waves in a string — the fundamental mode and the first 6 overtones. A standing wave, also known as a stationary wave, is a wave that remains in a constant position. This phenomenon can occur because the medium is moving in the opposite direction to the wave, or it can arise in a stationary medium as a result of interference between two waves traveling in opposite directions. In the second case, for waves of equal amplitude travelling in opposing directions, there is on...
