What is the importance of antenna in a wireless communication system?
For wireless communication systems, the antenna is one of the most critical components. A good design of the antenna can relax system requirements and improve overall system performance. An antenna is the system component that is designed to radiate or receive electromagnetic waves. In other words, the antenna is the electromagnetic transducer which is used to convert, in the transmitting mode, guided waves within a transmission line to radiated free-space waves or to convert, in the receiving mode, free-space waves to guided waves.
How long in meter is a typical radio wave which has a frequency of 560 kilohertz?
Oh, dude, you're asking about radio waves now? That's like, totally rad. So, to answer your question, a radio wave with a frequency of 560 kilohertz has a wavelength of about 536 meters. So, like, if you ever need to measure a radio wave's length while jamming out to some tunes, now you know!
What is the wavelength in meters of radio waves produced by a radio station with a frequency of 1400 kHz?
Wavelength of radio waves λ is speed of light c divided by frequency f.speed of radio waves c = 299 792 458 m/s and frequency f = 1,400,000 Hz = 1/sWavelength λ = 299 792 458 m/s divided by 1,400,000 Hz (cycles/sec)= 214.13747 meters.
How can you get the song for free it's called Space Mountain daytime version the music that is inside the ride while you ride the Space Mountain?
hi i want to learn how you can to go up to spaca in emerald version
Where can one listen to songs by Toby Keith for free?
Anybody wishing to listen to songs by Toby Keith could do so on websites such as as my space or cmt. Many of these websites such as jango allow you to listen to the songs free of charge.
What is the wavelength of a 300MHZ signal in free space?
The wavelength of a 300MHz signal in free space can be calculated using the formula: wavelength = speed of light / frequency. Given that the speed of light is approximately 3 x 10^8 meters per second, the wavelength of a 300MHz signal would be approximately 1 meter.
What is guided wavelength?
Guided wavelength, also known as effective wavelength, is the wavelength of light in a medium with a refractive index different from that in free space. It is the wavelength at which light travels in a waveguide or optical fiber, taking into account the refractive index of the medium. It plays a crucial role in determining the properties and behavior of light in these structures.
Guide wavelength and their relationship with free space wavelength?
One specification listed for waveguide or coax cable is its "velocity factor". This is the fraction that represents the speed of E&M within the medium compared with the speed of light in free space. It's always less than 1. For some media, as little as 65%. Since wavelength is (speed)/(frequency), lower speed directly implies shorter wavelength in the guide. This is important when the transmission line is not terminated in its characteristic impedance, and its 'electrical length' ... length measured in wavelengths ... directly influences the load characteristics at the source.
Why wavelength in guide is greaterthan free space wavelength?
In a waveguide, the effective wavelength is greater than the free space wavelength because the wave is confined within the boundaries of the waveguide, which results in a reduction in the phase velocity. This reduction in velocity causes the wavelength to appear longer in the guide compared to in free space.
The wavelength of electromagnetic radiation is inversely proportional to its?
Frequency. f=c/l Where, f=Frequency, l=Wavelength and c=Velocity of light in free space.
What is the meaning of the word free space?
Free space is a term used in classical physics. It is a region of space that has no gravitational or electromagnetic fields. It is used as an absolute standard.
What would be the wavelength of an electromagnetic wave having a frequency equal to the clock speed of an 800 MHz personal computer?
Wavelength = (speed of light) divided by (frequency).In free space, wavelength = (3 x 108) / (800 x 106) = 0.375 meterNote that 800 MHz is in the same general frequency range as many cellular telephone systems.
What is the link between radio waves and visible light?
Both are electromagnetic waves travelling at a speed about 300,000 km in one second in free space or in air medium. But radio waves have longer wavelength compared to that of light waves.
What are the two types of channels for transmitting electromagnetic waves?
Free space and guided medium.
Which wave in the EM spectrum has the shortest wavelength?
Gamma rays have the shortest wavelength. Electromagnetic wave is a kind of energy being propagated even through free space (vacuum). It is classified based on the mode of producing it as Radio waves, micro waves, infra red, visible, ultra violet, X-ray and Gamma ray. Out of these seven, radio waves have the lowest frequency and Gamma ray has the highest frequency. As frequency and wavelength are inversely related, radio wave would have the longest wavelength.
What is the velocity of electromagnetic energy?
In free space in a vacuum, EM energy travels at 300,000 km/sec
What is the wavelength when the frequency is 900 MHz?
The wavelength can be calculated using the formula: wavelength = speed of light / frequency. At a frequency of 900 MHz (900 x 10^6 Hz), the wavelength would be approximately 0.333 meters (333 mm) in free space.
