Dispersion of Light
Dispersion is the separation of light into a spectrum by refraction. The index of refraction is actually a function of wavelength. For longer wavelengths the…
Sunlight after Sunset
Lingering daylight after the sun is below the horizon is another effect of refraction. Light travels at a slightly slower speed in Earth’s atmosphere than…
Lecture on Mirages
Primary objective of this lecture is to present on Mirages. Mirages are caused by the refracting properties of a non-uniform atmosphere. It is an optical illusion caused by…
Presentation on Fiber Optics
Fiber optic lines are strands of glass or transparent fibers that allows the transmission of light and digital information over long distances. They are used…
Presentation on Snell’s Law
Principle objective of this lecture is to present on Snell’s Law. Snell’s law states that a ray of light bends in such a way that the ratio…
Lecture on Speed of Light and Refraction
Major objective of this lecture is to present on Speed of Light and Refraction. At an interface between two media, both reflection and refraction can occur. The…
Light: Holograms and Spectroscopy
Prime objective of this lecture is to present on Light: Holograms and Spectroscopy. A hologram the size of a sugar cube could hold enough information for about…
Polynesian Star Compass
Basic objective of this lecture is to present on Polynesian Star Compass. Here briefly focus on Polynesian Star Compass. The Hawaiians used a calendar based on the…
Lecture on Polynesian Navigation
General objective of this lecture is to present on Polynesian Navigation. For the ancient Polynesians, finding Easter Island must have been like finding a needle in a…
Sustainable Tourism
Sustainable Tourism is a continuous process and it requires constant monitoring of impacts, introducing the necessary preventive and/or corrective measures whenever necessary. It is tightly…
Astronomical Observational Techniques and Instrumentation
Main objective of this lecture is to present on Astronomical Observational Techniques and Instrumentation. Here derive resolution and sensitivity requirements for astronomical imaging- spatial resolution: Rayleigh criterion and…
