As most economies witness rapid expansion, demand for power is projected to increase significantly. Though most economies have invested in fossil fuels, renewable and sustainable sources present great possibilities for cheap and reliable electricity. One energy resource that ranks among the top renewable and sustainable sources is tidal energy.
Tidal energy or tidal power is a form of renewable energy obtained due to alternating sea levels. The kinetic energy from the natural rise and fall of tides is harnessed and converted into electricity. Tides are caused by the combined gravitational forces of the moon, sun, and earth. However, tides are influenced most by the moon. The moon’s gravitational force is so strong that it tugs the ocean into a bulge. The high and low tides create tidal currents, which are essential in the generation of this kind of energy, mostly prevalent in coastal areas.
The image produced a convex mirror is always virtual irrespective of location. The size of the image is always smaller than the object. In a plane mirror the distance of the object and the distance of the image is same. But in a convex the image distance is always less than the object distance.
