INTRODUCTION This is a useful circuit for various purposes. In this circuit a counter is activated when a continuously supplied light is been blocked. It uses a counter IC CD 4033.An LDR enhances the counting process. This circuit an be used for various applications such as to count products going over a belt‚ and for counting persons passed at a point etc The project is done as a prototype and its Real one can display a three to ten digit numbers and can count unto thousands.

Clocking the Speed of Light Why is the speed of light important? -Having a accurate number for the speed of light allows for accurate measurements of the universe around us -Even small inaccuracies make large differences when measuring the space between stars‚ planets‚ and galaxies -The more precise our measurement of the speed of light the more precise our measurements are of the universe because light is the universal measurement used Light as Infinite -Most scholars agreed that light

SPH3UC – Lesson 1 1. A) Amplitude is the distance between the equilibrium and the maximum displacement. In this wave‚ it would be from the equilibrium to the top of the crest or bottom of the trough. B) C) Speed: m/s Frequency: Hz D) Speed: because speed is constant and not affected by the change in frequency. Wavelength:0.4 Hz. 2. In transvers waves the motion of the particles is perpendicular to the direction of the energy. In longitudinal waves it they are parallel

How to Help the Environment In the world today‚ 4 trees are cut down every passing second; 360 every minute; 19‚200 every hour; 460‚800 every day; and over 11 billion every year. Unfortunately‚ Trees are constantly neglected and are cut down for fuel‚ ships‚ houses‚ etc. Because of this‚ Earth along with mankind is suffering from massive deforestations‚ which leads to species extinction‚ global warming‚ soil degradation‚ and loss of vaccines/medicine and biodiversity. To prevent this from happening
