Multiple Images with Plane Mirrors Introduction The number of images formed by two adjacent plane mirrors depends on the angle between the mirror. If  θ  (in degrees) is angle between the plane mirrors then number of images are given by, n=n = 360 θ − 1. We verify this formula in this experiment. Apparatus Two plane mirrors, protractor to measure angle, candle, matchbox. Procedure Take two plane mirrors (without frame). Place both the mirrors side by side and fix the junction where they meet with a cello tape. Now you will be able to open and close the mirrors like a book. Place both the mirrors at a small angle apart in the upright position on the floor. Place a lighted candle in the space between the two mirrors. You will observe many images of the candle which makes a beautiful scene. Now, by gradually decreasing the angle between the mirrors observe the images being formed. You will now observe more and more numbers of images of the candle. Similarly, if the angle between the mirro

Physics

What is physics? ArticleMediaAdditional Info HomeSciencePhysics Physics science Cite Share More WRITTEN BY Laurie M. Brown See All Contributors Emeritus Professor of Physics and Astronomy, Northwestern University, Evanston, Illinois. Coeditor of The Birth of Particle Physics. See Article History Physics, science that deals with the structure of matter and the interactions between the fundamental constituents of the observable universe. In the broadest sense, physics (from the Greek physikos) is concerned with all aspects of nature on both the macroscopic and submicroscopic levels. Its scope of study encompasses not only the behaviour of objects under the action of given forces but also the nature and origin of gravitational, electromagnetic, and nuclear force fields. Its ultimate objective is the formulation of a few comprehensive principles that bring together and explain all such disparate phenomena.   Bernoulli model of gas pressure As conceived by Daniel Bernoulli in Hydrodynamica
