The length and tension in the string are adjusted until standing waves are observed on the string. By knowing the tension in the string and the wavelength of the standing waves‚ the frequency of oscillation of the string and thus‚ the tuning fork is found. This value is then compared to a strobelight determination of the frequency. THEORY

    increased by increasing temperature (within certain limits) but not by increasing light intensity Photosynthesis involves the production of oxygen‚ and the uptake of carbon dioxide. These can be used as a measure of the rate of photosynthesis. This experiment will be an investigation into the photosynthetic rate‚ the rate at which plants produce all their own organic substances (food) using only light energy and simple inorganic substances. The rate of photosynthesis is dependent on environmental factors
