Frequency

INTRODUCTION Millimeter wave therapy is the exposure to a frequency that ranges from 30-300 GHz. This frequency is located in the radio frequency region of the electromagnetic spectrum. Due to the extremely small wavelength the frequency will only penetrate up to 2 mm of skin. In therapy the frequency is irradiated on certain parts of the tissue, depending on the specific treatment and energy it is deposited in the skin causing a variety of beneficial reactions. In the Former Soviet Union (FSU)…

He learned that all sound’s speed was affected by the medium it travels through (“sound”). He also learned other aspects of mediums and how they affect sound. The final scientist I will discuss is Daniel Bernoulli, and he made discoveries about frequencies…

Chapter 2 INTRODUCTION TO NOISE 2.1 SOUND: Sound is a form of energy that produces a sensation of hearing in our ears. Sound is produced by vibrating objects. The matter or substance through which sound is transmitted is called a medium. It can be solid, liquid or gas. Sound moves through the medium form the point of generation to the listener. When an object vibrates, it sets the molecules of medium around it vibrating. The…

Polarization in Antenna Polarization is the basic thing used in transmission antennas for the propagation and reception of the signals. As we know that antenna emits electromagnetic waves in the space for the communication purposes. These two types of waves as depicted by the name Electro-Magnetic is a combination of electrical and magnetics fields. These two waves are mutually orthogonal i.e. oriented at an angle of 90o with each other. The general wave form is given as Fig: Electromagnetic…

Chapter eight of the text Sound and Recording by Francis Rumsey and Tim McCormick, discusses the principles of digital audio, and contrasts digital with analog. The text also illustrates how digital and analog work together to produce desired sound. In the world of audio there are two types; digital and analog. Analog can be described as physical or tangible in a sense, being etched onto some type of media. Digital however, is a representation of the audio waveform, which is converted into a…

Sound travels through matter, which is a solid, liquid or gas. Sound travels in longitudinal waves. There is also a vibration that starts on an object, and this causes a vibration on all the molecules. When these molecules vibrate, they cause all of the other surrounding molecules to vibrate. This vibration will spread from molecule to molecule causing sound to travel. 1. What is a wave? A wave is a chain of vibrating molecules. In general, a wave transfers energy from one place to another. 2.…

with plunges up to 90 degrees. Be that as it may, it is computationally extremely concentrated. The movement calculations in ω - x area are innately parallel as far as frequencies. This favors us to respond to the call of exceptional process serious nature of ω - x movement on a parallel design…

Tzvat is a city in the Northern District of Israel. Located at an elevation of 2,953 feet, Tzvat is the highest city in the Galilee and in Israel. Due to its high elevation, Tzvat experiences warm summers and snowy winters.Tzvat is a famous vacation spot for its mild climate and scenic views. Tzvat’s current mayor is Ilan Shohat. In 2016, it had an estimated population of 33,636 residence. Tzvat is known as one of the four holy cities along with Jerusalem, Chevron, and Tiveria. It is mentioned…

did u know that sound is energy and how sound work? Read more to find out how sound is energy and how sound work. Sound is a release of energy the energy is released in the form of vibrations . How sound work is the vibrations emit from whatever has made the sound in what is known as a longitudinal wave.A longitudinal wave is a wave that travels in a single direction. Next how can we hear sound. We can hear sound from a longitudinal wave for example when a tree falls and energy is released…

The earliest of studies for speech sounds has been studied intensively since the early 1930s. Studies concerning the acquisition of phonemes are used in clinical practice and serve as a guideline to a practicing clinician. The earliest of studies came from 1931 by Wellman, Case, Mengert and Bradbury. Following Wellman’s findings, other researchers found new material and listing different ages in comparison to Wellman’s research. Sander (1972) discusses the various individuals that contributed to…
