Strong evidence for the wave theory of light First, we need to know: Interference When two ball-ended dippers are attatched to the vibrator of the ripple tank, two sets of circular ripples are sent out which pass through one another as shown in the image. Where the two waves are superposed in the same phase, […]

Parallel Universe – True Or Not?
Most of us are fascinated when we hear about parallel universe theory. Is it possible to have parallel universe? This is the first question that comes to the mind of a common man who hears about the theory of parallel universe. We have not yet explored one universe and now we are talking about many […]

Quantum Physics Parallel Universe
The food we eat, different people, stars, grains of sand; all come together to form the world we know. In this world, we are all truly unique and action we take has unique implications. However, if we go by the parallel universe theory we exist in more than one universe taking different actions with different […]

How An Optician Looks At Your Eyes: Eye Tests explained
It is strongly recommended we have our eyes tested every two years and even more regularly if we have past eye problems or already wear glasses or contacts. But how does an optician look at your eyes and decide what attention is needed? There are three areas an optician focuses on, which are the outer […]

Brief history of the nature of light
2 schools of thought concerning light Scientists have always been puzzled by the nature of light. In the seventeenth century there were two schools of thought concerning it. Sir Isaac Newton regarded light as a stream of corpuscles or tiny particles travelling in straight lines. The Dutch physicist, Huygens, held that light consists of […]

RELATIVITY AND ELECTROMAGNETISM ( Electromagnetic Waves )
Maxwell’s theory for electromagnetism: Magnetism and electricity produce energy waves, which radiate in fields with differing wavelengths. The most dramatic moments in the development of physics are those in which great syntheses take place, where phenomena which previousely had appeared to be different are suddenly discovered to be but different aspects of the same […]

The discovery of quantum mechanics (Photon)
The discovery of quantum mechanics (Photon) Photon First, we need to know : 1. Electromagnetic radiation: The energy of photons, having properties of both particles and waves. The major wavelength bands are, from short to long: cosmic, ultraviolet, visible or “light,” infrared, and radio. 2. Quantum: The amount of radiant energy […]
