What is a kooman antenna?
A vertical array of horizontal full-wave dipoles that are driven by transposed two-conductor line and backed with a parasitic reflecting curtain or horizontal dipoles.
Is a wave length horizontal or vertical?
If you can visualize whipping a length of rope tied to a fixed spot back and forth, you can then perfectly visualize radio frequency waves. If you whip the rope up and down the wave is vertically polarized. If you whip it back and forth horizontally, it is horizontally polarized. If you use a set of "rabbit ears" (dipole) to transmit a signal and hold it so the antenna points up and down, the radiated waves will be vertically polarized. To receive vertically polarized waves best, you need to use a vertically polarized antenna. The same holds true for horizontally polarized systems. This is a very simple but applicable explanation. There are other kinds of polarization such as "circular" as used in FM broadcasting and space communications. Just remember that the transmitting antenna's design determines the polarization of a radiated wave. See the ARRL Handbook 621.384 in your library for more detail.
How can you find the wavelength by observing a standing wave?
If you are looking for the simple answer, you measure its horizontal distance.
What is VERTICAL deflection?
As we mentioned earlier, a CRT can be used to graphically and visually plot an electronic signal,such as a sine wave. This is done by using a second set of deflection plates called VERTICAL-DEFLECTION PLATES
Can you compare the distance traveled by photon in gamma rays with the distance traveled in radio wave?
A wave length of gamma rays is 10 raised to minus 12. Means 1/1,000,000,000,000 meter. It means, you have 1,000,000,000,000, waves of gamma rays in one meter. Wave length of radio wave is 1000 meters. Speed of both of them same. So roughly, you take the speed of radio wave as straight line, forsimplicity of calculation. And straighten the gamma rays it would be minimum 1,000,000,000,000 times the speed of radio wave. ( Here you have taken length of radio wave 1000 times less, it means only 1 meter to correct the effect of straitening it, to be on safer side.) If you know the amplitude ofelectromagneticwave, you can get the unimaginable figure. In threedimensionalspace, wave may be traveling like spring and not as you draw on paper. Probably magnetic wave travel like coating on insulated wire. Which will be perpendicular to 'electric' wave. In that case, it should bechallenging task formathematiciansto calculate the length of such spiral wave.Probably something iscompressing the gamma rays to very small wave, so that speed of electromagnetic wave be a constant. The photons with maximum energy travel as a gamma rays. Then as gradually energy in photon decreases, it's wave length increases. It is a 'spectrum' and for your convenience that you have given them different names. Like gamma rays, x-rays, ultraviolet rays, light rays, infra-red, microwaves and radio waves etc. So better you wait for the edit of this answer by expert in this subject.
What is polarization of waves?
polarization of wave means to allow in one particular direction either it may be a horizontal or vertical and block other direction
Define polarization of an electromagnetic wave?
Polarization is the alignment of the transverse vibration in a single direction say in the horizontal direction or vertical direction or any other specific direction. Consider if venetian blinds were letting in light then horizontal light would pass but vertical light would be blocked and the passed light would be horizontally polarized.
Why vertical polarized wave is preferred over horizontal polarized wave in mobile radio communication?
1). Reflection of vertically polarized waves is less efficient, so vertical polarization is less susceptible to multipath fading due to ground-based reflection. 2). In order to avoid directional effects due to the radiation pattern of the receiving antenna (losing the mobile signal when the car turns a corner), the antenna wants to be vertical. That generally means vertical electrical polarization.
What is vertical and horizontal polarization?
Light acts like both a particle and a wave. These particle-waves are oriented in random directions. Polarisation filters basically filter out the randomly oriented waves, and ensure that only light that is 'polarized' in a certain direction can pass through.Horizontal polarisation is when the light waves are oriented horizontally, and vertical is when the waves are vertical. The same princaple applies to the whole EM spectrum.
Longitudinal wave do not exhibit in polarization or diffraction?
Longitudinal waves doesn't exhibit polarization or diffraction; these to features are for transverse waves.
Why a sine wave is a simple vertical line in a frequency domain?
A sine wave is a simple vertical line in the frequency domain because the horizontal axis of the frequency domain is frequency, and there is only one frequency, i.e. no harmonics, in a pure sine wave.
What is a kooman antenna?
A vertical array of horizontal full-wave dipoles that are driven by transposed two-conductor line and backed with a parasitic reflecting curtain or horizontal dipoles.
The phenomenon that sound wave fails to exhibit is - a Interference b Defraction c Vibration d Polarization?
The phenomenon that sound wave fails to exhibit is polarization.
Transverse wave nature of light is proven by?
polarization
Which phenomenon causes polarization of light?
Light is usually unpolarized, it becomes polarized when it passes through a polarizing filter. Light can be polarized because it travels as a transverse wave (of oscillating electric and magnetic fields) orthogonally to the direction of the medium in all directions, and polarizing filters polarize light in one plane. Polarized filters in the vertical plane only allow light in the vertical plane to pass through. Ex. polarized sunglasses have a polarizing filter in the vertical plane in order to minimize glare which is polarized light in the horizontal plane. and yes polarizing filters can be rotated to polarize light in other planes as well.
What does a polarization experiment prove about light?
it explains d wave nature of light.
What do you mean by polarisation of em waves?
That's the direction in which the ' E ' field of the wave points. It's always perpendicular to the direction in which the wave is traveling. But it could be horizontal, vertical, or any angle in between.
