![]() The precise manner in which images are formed by mirrors and lenses is discussed in an upcoming chapter on Geometric Optics and Image Formation.įigure 1.8 (a) Your image in a mirror is behind the mirror. Mirror images can be photographed and videotaped by instruments and look just as they do with our eyes (which are optical instruments themselves). Although these mirror images make objects appear to be where they cannot be (like behind a solid wall), the images are not figments of your imagination. If the mirror is on the wall of a room, the images in it are all behind the mirror, which can make the room seem bigger. The angles are such that the image is exactly the same distance behind the mirror as you stand in front of the mirror. We see the light coming from a direction determined by the law of reflection. When you see yourself in a mirror, it appears that the image is actually behind the mirror ( Figure 1.8). (credit c: modification of work by Diego Torres Silvestre) (c) Moonlight is spread out when it is reflected by the lake, because the surface is shiny but uneven. Only the observer at a particular angle sees the reflected light. (b) A mirror illuminated by many parallel rays reflects them in only one direction, because its surface is very smooth.

At the end of each Optics tutorial you will find Optics revision questions with a hidden answer that reveals when clicked. Each Optics tutorial includes detailed Optics formula and example of how to calculate and resolve specific Optics questions and problems. The following Physics tutorials are provided within the Optics section of our Free Physics Tutorials. Optics Physics Tutorials associated with the Angle Of Refraction Calculator We believe everyone should have free access to Physics educational material, by sharing you help us reach all Physics students and those interested in Physics across the globe. This allows us to allocate future resource and keep these Physics calculators and educational material free for all to use across the globe. We hope you found the Angle Of Refraction Calculator useful with your Physics revision, if you did, we kindly request that you rate this Physics calculator and, if you have time, share to your favourite social network. You can then email or print this angle of refraction calculation as required for later use. As you enter the specific factors of each angle of refraction calculation, the Angle Of Refraction Calculator will automatically calculate the results and update the Physics formula elements with each element of the angle of refraction calculation. Please note that the formula for each calculation along with detailed calculations are available below.
