  • 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...

  • 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...

    SOUND Vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear. All sounds are vibrations traveling through the air as sound waves. Sound waves are caused by the vibrations of objects and radiate outward from their source in all directions. A vibrating object compresses the surrounding air molecules (squeezing them closer together) and then rarefies them (pulling them farther apart). Although the fluctuations in air pressure travel...

    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...
