Comparing different types of equipment that uses lenses. This means that the magnification is positive but less than 1. These two types of lenses - a double convex and a double concave lens will be the only types of lenses that will be discussed in this unit of The Physics Classroom Tutorial. ��l=�a'O>��M���P��"\dI�A���A.������( �'�J�0΂'�c! floating elements) – Multiplied by number of lens elements • Energy/merit function – MTF, etc. H�4�� Ray 1: Ray 1: A ray parallel to the lens axis passes through the far focus of a converging lens or appears to come from the near focus of a diverging lens. There can be a convex lens which looks like a bubble bulging outward or a concave lens which has an inward bulging bubble shapes. – Lens curvature, width, position, type of glass – Some can be fixed, other vary with focal length, focus (e.g. And for the other procedures a Illumination Lamp was used. The Physics Convex lenses are converging lenses, and concave lenses are diverging lenses. A double concave lens is a diverging lens. ), we find the lens equation (21.4) Lenses Lenses are made of transparentmaterials, like glass or plastic. In the next section, let us discuss the different types of lenses. !��>��ú����Ȃ覷��-B��B��YK��f�P���#��(���g=�*���`F��r�Kc��Bl��'�[�K���I7H��!���԰ru���8�Z��}���s�V�L�Ɯ~�q�3 v�'� endstream endobj 7 0 obj<> endobj 8 0 obj<>/ProcSet[/PDF/Text]/Properties<>/ExtGState<>>> endobj 9 0 obj<>stream • s’ negative if image is on same side of lens/behind mirror: virtual image • focal length f positive for concave mirror and converging lens negative for convex mirror and diverging lens • object height h, positive • image height h’ positive if the image is upright negative if image is inverted • magnification m= h’/h , positive if upright, negative if inverted Terms and sign c To analyse these two types of lenses we studied the image form by one of them and compare it with the image formed by the other type of lense.

Physics 21900 General Physics II Electricity, Magnetism and Optics Lecture 19 –Chapter 22.4-6 Thin Lenses Fall 2015 Semester Prof. Matthew Jones. You can only shoot from one fixed focal length with this lens, meaning you have to move your physical body to get wide shots vs close ups. Standard lenses can typically have a maximum aperture range from f2.8 to f1.2. Observing the position of lenses in equipment. VOCABULARY: binocular camera eyeglasses hand lens microscope telescope MATERIALS: worksheet BACKGROUND: Lenses are used in our society in many ways. These are referred to as case 1, 2, and 3 images. This preview shows page 1 - 3 out of 3 pages. Convex (converging) lenses can form either real or virtual images (cases 1 and 2, respectively), whereas concave (diverging) lenses can form only virtual images (always case 3). The most abundant type of lenses is the spherical shape. Each of a lens’ two faces is part of asphere and can be convex or concave If a lens is thicker at the center than theedges, it is a convex, or converging, lenssince parallel rays will be converged tomeet at the focus. There are two types of the lenses which are the convex lens and the concave lens.

Types of lenses. OPTICAL LENSES 525 (21.3) Combining the two equations, we have that s/s f/(s f), and after cross-multiplying and dividing both sides by the product (s s f) and sim-plifying the result (try it! Lenses Abstract The purpose of this experiment was to study two types of Lenses, Converging & Diverging.

Converging Lens. %����   Privacy Ray 1: A ray parallel to the lens axis passes through the far focus of a converging lens or appears to come from the near focus of a diverging lens. They are usually hidden, … Try looking through eyeglasses meant to correct nearsightedness. H�0 Focal, length and lateral magnification was measured and compared in each procedure, to further, To find the focal length of two lenses taped together , we use Formula: 1/fc = (1/f1) + (1/f2). 2. APPLIED SCIENCE - PHYSICS (1A) POST LAB OBJECTIVES: 1. The classification of a lens depends on how the light rays bend when they pass through the lens.
