The document discusses the refraction of light and how it causes optical illusions. It explains that when light travels from one material to another of different density, it changes direction. Specifically, light bends toward the normal when moving to a denser material, and away from the normal when moving to a less dense material. The document provides instructions for an experiment to observe and measure the refraction of light through a glass block at different angles of incidence.
Modeling the Incidence Angle Dependence of PV Modules in PVsystKenneth J. Sauer
Presented at the IEEE Photovoltaic Specialists Conference (PVSC) in June 2014. The better conclusion is to simply use the resultant modeled, "custom" IAM profile for PVsyst (modeled via the Fresnels equations & Snell's Law presented herein) & avoid the ASHRAE model altogether.

This document describes an experiment to determine the refractive index of a prism material using Snell's law and by measuring the angle of deviation for different angles of incidence. The experiment involves measuring the angle of deviation for light passing through a prism at varying angles of incidence, plotting a graph of angle of deviation versus angle of incidence, and using the minimum angle of deviation to calculate the refractive index. The motivation was to quantify how much light is deviated when passing through a prism using measurable quantities like the angles of incidence, refraction, and the prism angle.
This document summarizes key concepts about light, including:
1. Light travels in straight lines and can be reflected or refracted. The law of reflection states that the angle of incidence equals the angle of reflection.
2. Refraction occurs when light travels from one medium to another of different density, causing the light to bend and change speed. This is demonstrated through experiments with glass blocks.
3. Prisms disperse white light into a visible spectrum due to the different wavelengths of light being refracted different amounts.
4. Mirrors form virtual upright images that are laterally inverted from the object, as shown through ray diagrams. Shadows are formed when light is blocked by an opaque object.
Light propagates in straight lines and can be reflected, refracted, and diffracted when interacting with matter. Reflection occurs when light hits a smooth surface and bounces back into the same medium at the same angle. Regular reflection occurs from plane mirrors where the angle of incidence equals the angle of reflection. Spherical mirrors can be concave or convex. Concave mirrors form real, inverted images, while convex mirrors form virtual, upright images. The mirror equation relates the focal length and distances of the object and image.

Optical fibers carry light along their length and work on the principle of total internal reflection. Light is kept in the core of the fiber due to the difference in refractive index between the core and cladding materials. Total internal reflection occurs when light traveling through the higher refractive index core strikes the core-cladding boundary at an angle greater than the critical angle, causing it to reflect back into the core rather than refracting out of the fiber. Optical fibers come in different types depending on their construction, propagation mode, refractive index profile, and applications in telecommunications and local area networks.
Prism is a portion of a refractive medium with two plane surfaces inclined at an angle. It causes light to deviate due to refraction. Prisms are used in ophthalmology to diagnose and manage eye alignment issues like strabismus. Key diagnostic uses include measuring the angle of deviation using prism alternate cover test and investigating binocular single vision through tests like the prism reflex test and prism vergence testing. Prisms are also used therapeutically to correct angles of deviation in conditions like esotropia and exotropia.

jQuery is a JavaScript library that makes HTML document manipulation and event handling easier. It works by allowing JavaScript code to select elements using CSS-style selectors and then apply methods to modify properties or trigger actions. Common uses of jQuery include showing/hiding elements, fading elements in/out, and animating element properties. Plugins extend jQuery's functionality for tasks like building menus, image sliders, and other interactive elements.
