Some lasers are referred to as being cw. What does cw mean?

A continuous wave or continuous waveform CW is an electromagnetic wave of constant amplitude and frequency; and in mathematical analysis, of infinite duration. Continuous wave is also the name given to an early method of radio transmission, in which a carrier wave is switched on and off.Information is carried in the varying duration of the on and off periods of the signal. In radio transmission, CW waves

Is there an equation for coverting Hz Hertz into Mbps mega bits per sec?

sinusoidal wave.A communications waveform may have a repeated shape. For example, the Ethernet can be measured in cycles per second Hz.Roughly speaking, and for measurement purposes, it can be considered a repeated "square wave," the same thing sent over and over again.The 100BASE-TX Ethernet has a specified data rate of 100 Mbps and it operates at 33 MHz.It can be shown that a square wave can

Transmission of wave through Dominant mode is - a distortion less transmission b generates undesirable harmonic distortion c having loss of power

well Nawraj, Transmission line apparatus for transmitting TE dominant electromagnetic waves is provided in accordance with the teachings of the present invention. The transmission line apparatus electromagnetic wave desired to be transmitted. The transmission waveguide is in fact so large with respect to the transmission frequency for the TE dominant electromagnetic wave selected that a plurality of waves

do radio transmission and TV transmission use same waves?

Radio waves are a type of electromagnetic wave. Since it is a wave, we can make an analogy between radio waves and water waves. The figure at the left shows a scenerio where water waves propogate from a single center point by the a ction of tossing a rock into the water. Radio waves cause electrons in an antenna to surge back and forth the same way that the ripples in a pond case the the water

Is there an equation for coverting Hz Hertz into Mbps mega bits per sec?

is a cycle. Plot the vertical height amplitude of a spot on the tire versus distance or time on a graph and you will have a sinusoidal waveform. Your house electrical power is a sinusoidal wave. A;square wave," the same thing sent over and over again. The 100BASE-TX Ethernet has a specified data rate of 100 Mbps and it operates at 33 MHz. It can be shown that a square wave can be represented by a

Why are sound waves called mechanical waves ?

is the physics of waves. Sound is a wave which is created by vibrating objects and propagated through a medium from one location to another. In this unit, we will investigate the nature, properties and behaviors of sound waves and apply basic wave principles towards an understanding of music.A wave can be described as a disturbance that travels through a medium, transporting energy from one location to another

What are electro magnetic radiations?

Electromagnetic EM radiation, also called light even though it is not always visible, is a self-propagating wave in space with electric and magnetic components. These components oscillate at right angles to each other and to the direction of propagation, and are in phase with each other. Electromagnetic radiation is classified into types according to the frequency of the wave: these types include

which is better AM or FM and why?

my explination the reason why the signal is "clear":All RC radios send out sine waves at 75MHz or 27MHz 75 million waves per second or 27 million waves per second This is you carrier signal. These sine waves look just like waves on an ocean is you plotted them on a graph.AM Amplitude Modulation works by amplifying or shrinking the carrier signal according to your input into the radio. The problem

What is meant by the term Polarisation?

A characteristic of the electromagnetic wave. Four senses of polarization are used in satellite transmissions: horizontal; vertical, right-hand circular; and left-hand circular. LNBs have a polarization setting to match the transponder orientation....PolarizationLight is a transverse wave, meaning that it oscillates in a direction perpendicular to the direction in which it is traveling. However, a

What are continuous waves?

A continuous wave or continuous waveform CW is an electromagnetic wave of constant amplitude and frequency; and in mathematical analysis, of infinite duration. Continuous wave is also the name given to an early method of radio transmission, in which a carrier wave is switched on and off. Information is carried in the varying duration of the on and off periods of the signal. In radio transmission, CW waves

Why are sound waves called mechanical waves ?

because they travel through medium and they cause disturbance in medium in form of crests n troughs...Sound waves are made by either mechanical vibrations in the air or elecrical energy converts in to mechanical vibrations which again creates waves in the air in the form of sound. So,sound waves are are called mechanical waves....Well The other major type of mechanical waves are called LONGITUDINAL WAVES

What is the difference between reflection and refraction?

discussed water waves. Remember what happened to the waves when they travelled obliquely between differnt depths? The distance between the waves front changed, indicating a change in wave speed. And because the speed of the waves changed, the direction of the waves also changed. This was called refraction.And for more information you can visit the source sites:http://en.wikipedia. org

what is diffraction?

Diffraction refers to various phenomena associated with the bending of waves when they interact with obstacles in their path. It occurs with any type of wave, including sound waves, water waves, and electromagnetic waves such as visible light, x-rays and radio waves. As physical objects have wave-like properties, diffraction also occurs with matter and can be studied according to the principles of quantum

What are microwaves?

Microwaves have wavelengths that can be measured in centimeters! The longer microwaves, those closer to a foot in length, are the waves which heat our food in a microwave oven. Image of child putting actually a microwave oven, or an oven that uses microwaves to generate heat. But what are microwaves?Microwaves are a form of electromagnetic wave. The most familiar kind of electromagnetic wave is visible

Which wave has greater wave length ground wave,sky wave?
