Benefits of radiations can be seen in the use of x-rays and treatment of cancer, wereas non-medical use of radiation can be seen in industries, fr detection of leaks and welding faults in different metal mediums. Aso for non-medical use, te rays are used for inspection on the production line to check emptiness or the thickness of materials like aluminum. (heng et al, 2000). Aart from nuclear power, tere are other ways to produce energy like hydroelectric, fssil fuel burning, slar and wind power. Al these methods have of advantages and disadvantages.

Sme of them will be depicted here. Hdroelectric power is free of cost, a water flow is easily available all around the world but the drawback is the amount of expenditure involved to build dams and huge water turbines. Frthermore, te environmental hazard for hydroelectric power generation is the disturbance of the ecological habitat of the aquatic life in the region. Fssil fuel is the best form of energy as it provides predictable and a constant power source but the major drawback falters this form I is the fossil fuel that is not a reusable or renewable source and is becoming scarce from the world at a very rapid rate.

Slar and wind power both have almost the same kind of advantage and disadvantage. Te setup for both is very expensive and is unpredictable in nature but the best advantage of these sources of power is the free and unlimited availability of power till the sun comes out and the wind blows. Mreover, fssil burning emits huge amount of carbon monoxide which in gives to the greenhouse effect, wereas wind and solar setups disturb the natural landscape of the area where they are installed (Nicolai, 2007).

Mny complaints have been lodged about the whirly sound, wich the wind farms make near the villages or residential areas. Tese complaints are properly document in researches that have been carried out by various environmentalists. Dffraction is defined as the apparent bending of light waves around obstacles to spread in different direction to give different effects. Lfe will be unimaginable without this natural phenomenon. Te of nature fr instance, wll not be seen as the sunlight will not be diffracted when in lands on the natural scenery.

Aso various real life applications involve diffraction. I diffraction was not available as a phenomenon, a present we would have been deprived of using CDs and DVDs, wuld have no. ..
