Optics Lab – Lenses & Mirrors Using the physics process of reflection and refraction, mirrors and lenses redirect light rays emanating from an object. Both for spherical mirrors and for lenses, the mirror-lens equations 1 = 1 + 1 holds. Lenses And how brain adapts to the image reflected or absorbed.

As we see the redirected light rays, we perceive them as coming from a source other than the object that sent them out and we see an image in the location where the light rays seem to come from. Then use the “thin lens” equations to calculate: endobj In this lab you will study spherical lenses and mirrors. A spherical mirror consists of a small section of the surface of a sphere with one side of the surface covered with a polished reflecting material, usually silver or aluminum.

Both can form images, however. The mirror is having one side reflective coating and on the other hand. LENSES AND MIRRORS SIMULATION Introduction The purpose of this activity is to study image formation by mirrors and lenses: the physical principles and the laws which describe them. Two prisms can bend light toward the principal axis acting like a crude converging lens but Clearly identify your final answer(s) rounded off to the proper number of significant digits in the chart at the bottom of the page. This topic is about Physical Science. Browse videos, articles, and exercises by topic. Show all your work. With a converging lens, paraxial rays that are parallel to the principal axis converge to the focal point, F. The focal length, f, is the distance between F and the lens. <> 4 0 obj <>/OutputIntents[<>] /Metadata 664 0 R>> @���6�Gp���P%�E�z^b���v��b�]8��A`mtnQ�����z��Y|2�T��-� $���g֐�G$shȅ��4��w� +Ƚ}|�#�|*�΢8�Zy�[��F=��T�S��*�6Hb SK_��J��,q���e��,�� <> It is known that there is a formula called Lens formula (v 1 u 1 f 1 = + ) which stated the relationship between object distance u, image distance v and the focal length of a spherical lens. At the end of the presentation, the ss will be able to correctly differentiate between the three types of mirrors. The core differences between the mirror and lens would be due to its construction and working. Physics 30: Chapter 5 - Lenses & Mirrors Exam Name: _____ Date: _____ Mark: ____/25 Written Response. For each case, draw the 3 principal rays to locate the image. Science Worksheets and Study Guides 8th Grade. Images in flat mirrors are the same size as the object and are located behind the mirror.
