Ray Optics The wave model of Light has one serious drawback, though: Unlike other wave phenomena such as Sound, or surface waves, it wasn‟t clear what the medium was that supported light waves. Giving it a name – the “luminiferous aether” – didn‟t help. James Clerk Maxwell‟s (1831 – 1879) theory of electromagnetism, however, showed … Read more
Unveiling the Mysteries of the Deep: A Journey into Oceanography The Earth, a vibrant tapestry of life and landscapes, holds within its embrace a vast and enigmatic realm â the ocean. Covering over 70% of our planet’s surface, this watery expanse is a cradle of biodiversity, a regulator of climate, and a source of countless … Read more
Electro Magnetic Induction When a DC current passes through a long straight conductor a magnetising force, H and a static Magnetic Field, B is developed around it If the wire is then wound into a coil, the magnetic field is greatly intensified producing a static magnetic field around itself forming the shape of a bar … Read more
A tsunami is a very long-wavelength wave of water that is generated by sudden displacement of the seafloor or disruption of any body of standing water. Tsunami are sometimes called “seismic sea waves“, although they can be generated by mechanisms other than Earthquakes. Tsunami have also been called “tidal waves”, but this … Read more
Harnessing the Ocean’s Thermal Gradient: A Deep Dive into Ocean Thermal Energy The Earth’s oceans are vast reservoirs of energy, absorbing and storing immense amounts of solar radiation. This energy manifests as a temperature difference between the warm surface waters and the cold depths, a phenomenon known as the ocean thermal gradient. This gradient, a … Read more
