Optical illusions

A ray of light travels in a straight line. This is true until it passes from one medium (eg. air) into another medium (eg. glass) of a different optical density. When this happens, the ray of light changes speed causing it to bend either towards or away from the normal which is an imaginary line at 90 to the interface between two mediums. This is called refraction. How much it bends depends on the refractive indices of the two mediums which is a ratio of the speed of light in one medium…

2.) A: Although life is often filled with chaos and unpredictable futures, I do agree with the author Steven Johnson. I believe that as unpredictable this world is, that we must do our very best to predict to the best of our ability the effects each new innovation may bring. I would never have recognized some of these connections that have been made in this book between two things that could be so different. My favorite one being the air conditioning. The push for the invention of the air…

Optical fiber thin as hair is everywhere on this planet, carries an enormous amount of information from place to place. There are a number of desirable characteristics of the optical fiber for conveying this information. They have the ability to carry large amounts of information, a low cost and have the immunity from electrical wiring and wireless communication link a number of disturbances that can afflict. Advantages of optical fibers for transmitting information from place to place, it…

for mobile network, however optical network is required for the communication of large amount of data in short period of time. Many smarter devices are being added to network to fulfil consumer’s demand. There are many complications and strains have arisen to optical networking with the advancement of technology. some management and security techniques can be adopted to get the best out of network infrastructure. More security and control mechanisms are added into optical networks for the…

In today’s world sensors especially optical sensors have many emerging applications beginning from the medical diagnostics to detect the pollution in the environment. Because of these wide range of applications the challenges faced to design, proper functioning and maintenance of an optical sensor requires immense knowledge of optical, material, and environmental properties that could affect sensor performance in all aspects. The wavelength range of the laser, interactions between the signal…

dispersion, intramodal dispersion, bandwidth limitation, polarization mode dispersion, optical cross talk, and attenuation issues. Finally, this paper will end with a mention of current research and future research in the field and then a brief…

FIORD is an acronym that stands for; Facts, issues, options, recommendation, and decision. It is used to help people with ethical dilemmas and complications. This can be extremely beneficial in the work place. Though, it can also be extremely beneficial in every life decisions. Today, I would like to discuss my experience with community day using the FIORD Method. I will start with the facts. For community day our dignitas class went to Hawks ridge. Our role was to cut down Buckthorn, which is…

in someone. Empathising with her struggles from an early age made me aware of the reliance on our eyesight. Ultimately I was motivated to attend a talk regarding optometry which enhanced my knowledge of the course and gave me a chance to operate optical instruments. Acknowledging my ambition beforehand made me choose A-level subjects related to optometry. I am very passionate about biology as my ability to make connections between what I have learnt and the biological processes that occurs in…

Ames Room What is an Ames room? An Ames Room is a room that is used to create a visual illusion due to its slanted figure. While the room gives an appearance of a square-shaped from the viewers’ observation, it actually has a trapezoid shape. This effect works by developing a distorted room to create the illusion of a intense modification in its size. The illusion that is projected leads the observer to believe that the two objects that are in the same depth of area, when in reality the subject…
