solve above these problems‚ we create a device in which the lights glow in night and in day time‚ they off automatically and don’t glow. Due to use of it‚ we can solve above problems and can also save electricity and men’s power. PRINCIPLE This project is based on Light Dependent Resistance (L.D.R.). Light Dependent Resistance [LDR] is a resistance‚ in which opposing power of current depends on the presence of quantity of light present‚ i.e. the resistance of LDR increases or decreases‚ according

8th physics light reflection refraction eyes defect and dispersion The ray of light which falls on the mirror surface is called incident ray. The point at which the incident ray strikes the mirror is called the point of incidence. The ray of light which is sent back by the mirror is called the reflected ray. The ‘normal’ is a line drawn at right angles to the mirror surface at the point of incidence. The angle between incident ray and normal is called the angle of incidence. The angle between

If people think about how times were back in the 1350’s compared to now you would see the gratefulness in people’s everyday life. Life back in the 1350’s was rough‚ especially during the Black Plague. The plague was unexpected and happened in a days just to last for years‚ killing thousands of people with excruciating pain cutting the population of England and multiple other countries. We the people of the United States are lucky to be clean and free of deadly viruses. The Black Plague was one of

The Physics of Baseball The sport of baseball has been around for over two hundred years‚ roughly since the 1800s. Invented by a man named Alexander Cartwright. It is known as “Americas past time.” Baseball is the national sport of the USA. The first baseball game played was in New York on June 19‚ 1845. And is played by thousands of people throughout the years. Much like any sport‚ it has changed with time. The first rulebook of baseball was issued in 1877. And it has been changing every year

Experiment 1: Simple Harmonic Motion Dominic Stone Lab Partner: Andrew Lugliani January 9‚ 2012 Physics 132 Lab Section 13 Theory For this experiment we investigated and learned about simple harmonic motion. To do this we hung and measured different masses on a spring-mass system to calculate the force constant k. Simple harmonic motion is a special type of periodic motion. It is best described as an oscillation motion that causes an object to move back-and-forth in response to

Physics in My Daily Life “Write an essay of 1500 words‚ double spaced‚ in standard fonts ‚ giving credible references on the use of physics in your daily activity. You need to mention 5 or more activities where physics is used. Please follow the APA format.” As a senior in college‚ I lead a rather busy life. My days usually follow the same routine and pattern. I wake up at 7am everyday‚ so I am rather tired. To get going in the morning‚ I usually drink a cup of coffee. Then I attend my classes

Lunar phases‚ tides‚ and seasons all affect life on Earth. You can see these changes everyday‚ whether you’re watching the news or looking at the moon. Changes in weather‚ water height‚ and even the light from the moon can dramatically change daily life. Lunar phases aren’t actually caused by the moon changing shape. It’s caused by the moon changing position. As Earth rotates around the sun‚ it casts shadows on the moon‚ creating the eight different moon phases. A tide is the rising and falling
