The mirror equation enables one to calculate the image position from the object position and the radius of curvature of the mirror. spherical mirror can also be characterized by its focal length.
Mirrors, which form images by reflection, are important components of telescopes; lenses, which form images by refraction, are also important components of many optical systems, including (refracting) telescopes.
Terms and sign conventions for lenses and mirrors object distance s, positive image distance s’ , positive if image is on side of outgoing light, i.e. same side of mirror, opposite side of lens: real image s’ negative if image is on same side of lens/behind mirror: virtual image focal length f
A mirror is a reflective surface that does not allow the passage of light and instead bounces it off, thus producing an image. The most common mirrors are flat and called plane mirrors. These mirrors are made by putting a thin layer of silver nitrate or aluminium behind a flat piece of glass.
In Chapter 22, we looked at how light is an electromagnetic wave, made up of oscillating electric and magnetic fields propagating through space. In this chapter, we look at the reflection of light, how light interacts with mirrors, and how mirrors can be used to form images.
When drawing lenses in our sketches, we need to put in a principle axis, just like mirrors. You also need to add in a principle plane, line that is perpendicular to the principle axis and runs length wise through the middle of the lens. We will be assuming that all refraction happens when the light reaches this.
This video tutorial lesson explains how to use the mirror equation and the magnification ratio to solve Physics word problems. Four examples are discussed.
