  • Man Made Natural Disaster: Acid Rain

    Man Made Natural Disaster: Acid Rain

    Ozone depletion, greenhouse effect, and acid rain are man-made disasters. The ozone layer is the part of the Earth's atmosphere which contains relatively high concentrations of ozone (O3). The cause of ozone depletion is the presence of Chlorofluorocarbons (CFCs) and related halocarbons gases in the atmosphere. In the presence of Ultraviolet light, these gases dissociate, releasing chlorine atoms, which then go on to catalyze ozone destruction. The greenhouse effect, on the other hand, is a

    Introduction In this experiment we are trying to examine and fine the interference of light waves and to observe how the interference pattern depends on the geometry of the apertures. Interference occurs because we combined two lights waves, one is coming from each slit. The definition of interference in physics is the combination of two or more electromagnetic waveforms to form a resultant wave in which the displacement is either reinforced or canceled. In this
