A literary analysis of the essay "A Room of One's Own" by Virginia Woolf is presented. It discusses how windows, reflection, and refraction are used to represent creativity as well as her position as both a subject and observer. The author goes on to examine Woolf's use of indirect discourse and stream of consciousness narration.

Chapter 6 of the book "Uncovering Student Ideas in Science: Another 25 Formative Assessment Probes," Volume 3, by Page Keeley, Francis Eberle and Chad Dorsey is presented. It focuses on an assessment probe which aims to evoke the ideas of kindergarten students regarding the reflection of light. The assessment probe examines how the students use ideas on light to explain how people see objects in a mirror.

Chapter 10 of the book "Water: Fascinating Facts and Oddities That Boggle the Mind," by Frank Dixon Burk is presented. It explores natural phenomenon of rainbow. Ancient philosopher Aristotle tried to answer this phenomenon as an occurrence that happens due to the odd grouping of clouds. Widely accepted theory about rainbow is related to the reflection. It states that a rainbow is the result of a multitude of raindrops that act like prisms in reflecting the Sun's light.

Chapter 3 of the book "Light: Stop Faking It! Finally Understanding Science So You Can Teach It" is presented. It explores the good uses of light, particularly with various optical instruments like antennae and lenses. It also explores on how telescopes work such as the refracting telescope and a reflecting telescope.

The article focuses on principles of optical image formation. An optical image is a spatial map of emissivity, reflectance or transmittance. Image formation and the associated instruments may be understood from the concept of rays. The theory related to paraxial rays can be used for finding the location and size of the image, obtaining a first approximation to the brightness of the image. Paraxial ray tracing is done by refraction through a surface and transfer to the next surface. The image of an extended object can be considered as the summation of the images of all points, point-spread function, that comprise the object.

The article presents information on Gaussian Optics. The ray-tracing equations used in the theory of Gaussian optics are correct to first order in the inclination angles of the rays and the normals to refracting or reflecting surfaces. When higher-order approximations are used for the trigonometric functions of the angles, departures from the predictions of Gaussian optics will be found. No longer will it be generally true that all the rays leaving a point object will exactly meet to form a point image or that the magnification in a given transverse plane is constant. Such deviations from ideal Gaussian behavior are known as lens aberrations.

The article focuses on thin film analyzers. The term thin films has been applied to coatings whose thicknesses range from less than an atomic monolayer to films on the order of 1 mm thick. A very important application of thin films is in the field of semiconductor electronics. The partial reflection of light at the interface between two materials of different index of refraction permits the measurement of the thickness of a transparent film. The technique of ellipsometry is suitable to measurement with great precision of the thickness and index of refraction of thin, nonabsorbing films on highly absorbing substrates.

This article presents information on electro-optical filters. An optical filter that can be electrically tuned to a desired wavelength is known as an electro-optical filter. There are various types of electro-optical filters that have been reported so far. Typical filters are based on directional couplers, distributed Bragg reflectors, Fahry-Perot resonators, Mach-Zehnder interferometers, and polarization mode converters. Among them, the directional coupler- type filter has a single passband in transmission and can send the selected wavelength to the other port without inherent light reflection. This makes it possible to integrate other components into the coupler structure and to prevent optical noise from entering the system.

This article focuses on attenuators. Attenuators are linear, passive or active networks or devices that attenuate electrical or microwave signals, such as voltages or currents, in a system by a predetermined ratio. They may be in the form of transmission line, strip line or waveguide components. Attenuators are used to provide protection, reduce power, and extend the dynamic range of the test equipment. In choosing an attenuator, the frequency range of operation should be considered since the accuracy depends on the frequency. Attenuation involves placing resistive material to absorb the signal's electric field. This means, there will always be some reflection. So, attenuators must be designed to minimize reflection.

The plane wave is the most fundamental electromagnetic wave and is a particular solution of Maxwell's equations. It will be used as an example to develop the fundamentals of electromagnetic waves in dielectric media including solutions to Maxwell's equations, phase velocity, group velocity, polarization, boundary conditions, and total internal reflection, which makes it possible for optical signals to propagate and be guided in waveguides. Based on the concepts developed for plane waves, planar one-dimensional waveguides will be presented, followed by the study of rectangular two-dimensional waveguides. Fundamental concepts for wave propagation in waveguides such as modes, orthogonality and completeness of modes, dispersion, and losses are discussed. A review of waveguide-based directional couplers, the fundamental building block for planar waveguide filters, is followed by a brief presentation of star couplers and multi-mode interference couplers, which are important for multi-port filters. The chapter concludes with a discussion of material properties and fabrication processes that are important to filter design, with a focus on planar waveguide implementations.

A science experiment demonstrating reflection and refraction is presented. A list of materials is provided, along with preparation and safety considerations, specific procedures, and discussion topics. It is concluded that light changes speed and direction when it passes obliquely from one material to another which is called refraction while the angle of outgoing light is always equal in degrees with angle of incoming light when it is reflected.

The poem "Narcissus of the Damned" is presented. First Line: One day Martin can't; Last Line: “I think you love me."

Chapter 6 of the book "Energy Conservation Guidebook" is presented. It explores the characteristics of light. Topics discussed include basic terms in light including candela or candlepower, lumen, the unit of illumination called lux, reflected light, reflection factor, the light reflected from a surface and characteristics of daylight.

The article talks about René Descartes as a scientist. Descartes established the fundamental laws of reflection in optics wherein the angle of incidence equals the angle of reflection. He coined the Cartesian model of the universe, which is made up of swirling vortices and was the accepted model of the universe until Isaac Newton's discovery of theory of gravity. He also established the idea of primary and secondary qualities of the corpuscles.

Information on light shows in the sky from a chapter of the book "DK Guide to Weather," is presented. It relates that the rainbow is a circle of colour produced by sunlight falling on rain. It outlines the best time for seeing a rainbow and how to create one's own rainbow with a garden sprinkler on a sunny day. It explains why different colours are seen in rainbows. It discusses icebows in frozen polar regions, fogbow during a foggy day and the solar corona.
