Deviation of angle of incidence

In optics, a prism is a transparent optical element with flat, polished surfaces that refract light. The exact angles between the surfaces depend on the application. The traditional geometrical shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use “prism” usually refers to this type. Some types…

Batman Begins Opening Scene

In the opening scene of Batman Begins it shows hundreds of bats flying in the sky. This is to set an ominous tone for the audience and to show a sense of danger. This is also done by the high pitched sound of the bats giving a panicked and fearful tone. The lightening in this…

The Most Useful (or Important) Scientific Invention

The microscope is considered one of the most useful and important scientific inventions known to ‘man’. The microscope was invented by Anton van Leeuwenhoek during the seventeenth century. Leeuwenhoek was not a scientist by profession. Initally he made a living selling clothes and buttons, but spent his spare time grinding lenses and constructing microscopes of…

The Microscope: Science’s Greatest Invention

The microscope has been one of the greatest inventions in the history of science and has had the most impact on the course of science. Ever since the first microscope was invented in 1590, they have improved our knowledge in basic biology and biomedical research, as well as many other things, all of which are…

Report on Sir Isaac Newton

Sir Isaac Newton was an English mathematician and physicist. He was considered one of the greatest scientists in history. Newton was also the culminating figure in the scientific revolution of the 17th century. Newton was best known for his discovery that the force called gravity affects all objects in space and on earth. .Isaac Newton…

The Human Eye and the Colourful World

Q 1. What is meant by power of accommodation of the eye? Ans. The ability of the eye lens to adjust its focal length, so as to clearly focus rays coming from distant as well a near objects on the retina, is called the power of accommodation of the eye. Q2. A person with a…

Balloon Cars

Repulsorlifts as a Method of Stable Magnetic Levitation| Repulsorlifts were used in the study to find out if they can be used to replace the wheels of a conventional car. It was hypothesized that it will be able to lift a car using magnetic repulsion forces. The different magnets were tested individually with the usual…

Photodiode Process

* a type of photodetector capable of converting light into either current or voltage, depending upon the mode of operation. The common traditional solar cell used to generate electric solar power is a large area photodiode. * a semiconductor with a p-n junction PRINCIPLES OF PHOTODIODE * Photons is the source of its energy *…

Free Space Optics

ABSTRACT: FSO may sound new and experimental but in fact it predates optical fiber and has its roots in wartime efforts to develop secure communication systems that did not require cable and could withstand radio jamming. FSO has been around for more than a decade, but it is only recently that interest in this technology…

Optical Training Manual

An Occupational Lens (or Enhanced Reader) is a reading lens that has a Degression zone to incorporate the Intermediate prescription (and sometimes, depending on prescription, a good DV portion) Why dispense an Occupational Lens, instead of a Reading pair of glasses? With more and more people using Computers, Laptops and Smartphones, we demand more from…

Microscopy and the Metric System

1. List the components of the compound microscope and their function. 2. determine the total magnification given that you are using a compound microscope with the following objectives: 4x, 10x, 40x, and 100x 3. what is meant by the depth of field? 4. what is meant by the field of view? 5. describe the process…

Diffraction and Interference

Purpose: The aim of doing this experiment was to examine diffraction and interference effects of light passing through various apertures, and use the diffraction patterns obtained by single and double slit apertures to find the wavelength of the light source used. Theory: We know that light can be described by two theories, namely the particle…

Refractive Index

Abstract The purpose of this lab was to learn how to properly use the refractometer and determine the composition of 2-propanol and water in an unknown binary mixture. This was carried about by measuring the refractive index of each substance at different temperatures (22°C, 34°C, 46°C, 58°C and 70°C) using the Abbe refractometer. By obtaining…

The Power of a Magnifying Glass

The magnification of a magnifying glass depends upon where it is placed between the user’s eye and the object being viewed, and the total distance between them. The magnifying power is equivalent to angular magnification (this should not be confused with optical power, which is a different quantity). The magnifying power is the ratio of…
