Lab Report 2 Name: Waqas Kampulvi Frequency & wave length Experiment Aim: The wavelength and frequency of light are very closely related‚ our aim for this experiment is to determine the relationship between wavelength and frequency and the impact or change in the numbers as a result. Apparatus: Loud Speaker Signal Generator Ruler Microphone Audio Analyzer Plastic Tube Supporting Research: All sound waves which are travelling through the air are in fact longitudinal waves (running lengthwise

remembers clues of his past which mostly frighten him. The clue of the dog reminded him of his fear of dogs and how he and his father wondered into the forest for a strange reason and got attacked by a dog. Another example would be the clue of Amy Hertz. It was because of her phone nerd call about his family which made him suspicious. But I felt he was more afraid then inquisitive. Afraid to find something that would change his life forever.

same from which ever type of atom they had originated. In the end‚ he found that the rays consisted of very light‚ negatively charged particles‚ which were the foundation of all atoms. These particles are known today as electrons. In 1888 Heinrich Hertz built a device that produced and detected UHF radio waves. The device proved his theory of the existence of electromagnetic waves. During his research he also found depending on frequency that some waves could be transmitted through some materials

wireless era was started by two European scientists‚ James Clerk Maxwell and Heinrich Rudolf Hertz. In 1984‚ Maxwell presented the Maxwell’s equations by combining the works of Lorentz‚ Faraday‚ Ampere and Gauss. He predicted the propagation of electromagnet waves in free space at the speed of light. His theory was accepted 20 years later‚ after Hertz validated electromagnetic wave (wireless) propagation. Hertz demonstrated RF generation‚ propagation and reception in the laboratory. His work then continues

Introduction According to the United States Workforce Investment (2015)‚ information literacy can be defined as an individual’s ability to learn how to read‚ write‚ evaluate and use information accordingly to solve problems as an independent learner (Welsh & Wright 2010). However‚ we can say Information literacy creates some basis of lifelong learning and also helps people when they need a particular information. The use of Technology has increased rapidly around the world‚ especially in the last

experiment‚ which showed that light mimics a wave‚ extinguished some of these early views. However‚ in 1887‚ Heinrich Hertz – who is‚ coincidentally‚ perhaps better known for definitively proving the existence of James Maxwell’s and David Hughes’ theorized electromagnetic “light” waves by detecting radio waves around the same time – breathed new fire into the seeming ambiguity. Hertz observed that shining ultraviolet light on electrodes causes electric sparks (electrons being released) more rapidly

Before beginning our research on radio waves‚ to us‚ radio waves were just waves going through the atmosphere‚ carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves‚ and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves‚ which represent voice and other
