PHYSICS PROJECT TO STUDY THE OPTICAL LENS OF A HUMAN EYE Eyes are organs that detect light‚ and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment; regulates its intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an image; converts this image into a set of electrical signals;

PHYSICS II ELECTRICITY‚ MAGNETISM‚ SOUND‚ AND LIGHT SERIES CIRCUIT In this unit you’ll begin learning how to analyze circuits. Circuit analysis means looking at a schematic diagram for a circuit and computing the voltage‚ current‚ or power for any component in that circuit. Closely related to the task of circuit analysis is the task of troubleshooting‚ which means figuring out what is wrong in a circuit that is not working correctly. Analyzing and troubleshooting go hand in hand; when a circuit

Investigating Newton’s 2nd Law of Motion using an Air-track Introduction: My experiment is investigating the Newton’s 2nd law of motion by using an Air-track. The air-track can make the trolley frictionless by testing the velocity with different weights and shows that F=ma. Research question: How much acceleration does the frictionless trolley has? Aim: Use the air track to measure the acceleration of the no friction trolley by hanging with different mass of weights. Apparatus: *

Daily Use of Physics Jason L. McDuffy University of Memphis Physics 1 (online) Project 1 Daily Use of Physics Physics is considered to be a powerful lens that helps people view the everyday world. Physics is reflected in the everyday phenomena‚ puzzles and toys that offer a variety of interesting challenges leading to deep and interesting problems that derive from science and mathematics. It provides us an understanding of energy‚ motion and explains these facts as

Introduction I have chosen to investigate a factor that affects the output of a potential divider circuit. A potential divider is resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage. A resistor is a device having resistance to the passage of an electric current which affects the output voltage (Vout). The factors that I could investigate are changing the resistance of r2 and record the output (Vout)‚ or use a light-dependent resistor (LDR) and change

INTRODUCTION On the job training or and OJT is one method by which students is given a chance to apply the theories computations that they have learned from the school. It also helps the students to acquire relevant knowledge and skills by performing in actual work setting. Colleges and universities require their students to undergo such training within a specific number of hours as part of the curriculum. For the students‚ an OJT or internship program provides opportunities togo through the actual

Motion NCERT Chapter Questions and Answers and other Q & A Q1: An object has moved through a distance. Can it have zero displacement? If yes‚ support your answer with an example. Answer: Yes an object can have zero displacement even though it has moved through a distance. It happens when the object moves back to its original position i.e. final position coincides with the starting position. Example: Suppose an object travels from O to C and then comes back to original position O. Total

Introduction Mosquito coils are widely used as mosquito repellent. The major active ingredients of most mosquito coils are pyrethrins‚ accounting for about 0.3 – 0.4% of the coil mass. When a Mosquito coil is burnt‚ the insecticides evaporate (pyrethrin‚ PAH‚ aldehyde etc.) with smoke‚ which prevent the mosquito from entering the room and harm those already in the room. The remaining components of mosquito coils include organic fillers‚ binders‚ dyes and other additives capable of burning well without
