Radio frequency

Waves are caused by vibrations. There are two types of waves, transverse, and longitudinal waves. The moving particles in transverse waves travel at right angles to the direction of transverse. Some examples of transverse waves are light waves and radio waves. A longitudinal wave is also known as a compression wave. The moving particles move back and forth in the same direction as the wave. An example of this is a wave moving through a stretched out slinky. Image 1: There are two areas in a…

In the first place let begin by saying what is the (LRAD)? It is The Long Range Acoustic Device. Which is a loud megaphone/microphone or speaker to convey important messages to individuals who makes loud noise and disturb the environment. Certainly, the LRAD is not a less lethal weapon. Of course, the LRAD is used to get the attention of a large crowd or a criminal is about to break the law by disturbing the peace. The LRAD once in operation will get the attention of the troublemaker, prevent…

its inverse, the frequency (μ). To acquire this value, the ideas of electromagnetic and cosmic radiation have to be accounted for. Because all objects in our universe and anything between us and the receiving planet emit some sort of electromagnetic radiation, extensive research has been put into determining the range that incurred the least amount of noise. As a society, we base our daily life on radio communication — television, cell phones, and everything in between use frequencies from 0.5 -…

3.1. GENERAL SPECIFICATIONS The project is an Arduino- based project and is based concerning radio frequency according to ship then get hold of the data. The RF transmitter and grantee each work at a 433 MHz to send then get hold of data. We will be adding the use of an ultrasonic, which measures the scale in conformity with an object, through the usage of echo waves. An LCD show choice is aged to show the statistics managed with the aid of the Arduino. The dictation is computerized therefore…

Topic: Radio Frequency Identification (RFID) -Pros & Cons 1.0 Explanation of marking justification. The topic of the pros and cons of radio frequency identification (RFID) had been evaluated during the presentation session and marks had been given. There are two categories in marking criteria which are content and presentation. For the content which 60 marks in total, there are divided into details which is research, relevance, topicality, and conclusion. Meanwhile, for the presentation which…

Firstly, its advantages include being safe and painless. Unlike X-ray, MRI scanners do not use ionizing radiation; instead they use magnetic fields and radio waves which are harmless and can be absorbed by the body without causing mutations because radio waves have a low frequency and thus a low energy that doesn’t cause harm. Secondly, the pictures that are created by the MRI are precise which allow definite analysis of the image by a medical professional; especially…

RFID TECHNOLOGY Radio-frequency identification (RFID): RFID Technology is a wireless electromagnetic field that is used to transfer data, or to identify people or objective, for the purposes of automatically identifying and tracking tags attached to objects. RFID is very fast, reliable and does not require any physical sight or contact between reader and scanner and the tagged items. There are some tags contains electronically stored information. It refers to small electronic devices that…

Introduction: The lab experiment on Fabrication and Microwave Frequency Measurement of a ring Resonators was about finding the relative dielectric constant and the response of a ring resonator. These values are found by using a ring resonator and setting a frequency signal to the ring to resonate the signal. This lab also shows how to make the ring resonators from paper or any type of electric device from fabrication. Fabrication is used to print electric devices such as printed circuit boards.…

like: supermarket items(known as the barcode), inside people, pets, computers, phones, etc. to track them down, read their data and transfer files to and from. An RFID tag is a Radio frequency identification device(Tag You're It 72). It contains radio frequency which means anyone with an RFID tag reader can receive radio waves and see whatever the RFID tag contains. Even Though RFID’s track kids and pets that ran away from home, they should not be used because they are dangerous to personal…

1 Introduction Interferometry is a measurement technique which utilizes the interference of waves in a medium to cre-ate interference patterns [5]. In general, the waves can be light, sound or radio waves. The interference pattern is detected by a photodetector and it provides some useful information about the properties of the object or phenomenon under test. Interferometers are used to make very small measurements that cannot be achieved with any other method. An important…
