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.
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.
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.
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.
Digital signal in free space?
Electromagnetic radiation (radio waves, light) travels in free space. This radiation can be encoded to carry either analog information or digital information. An example of analog-encoded radiation is that emitted by an AM radio station. Examples of digitally-encoded radiation are a wireless home computer network and the next generation of television broadcasting.
What is the wavelength of 300MHz electromagnetic wave in free space?
Wavelength = 1/Frequency
What is the wavelength of a 900 MHz signal in free space?
The wavelength of a 900 MHz signal in free space is approximately 0.333 meters. This can be calculated using the formula: wavelength = speed of light / frequency, where the speed of light is 3 x 10^8 meters per second.

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.
Does thr color of light depends upon its wavelength or frequency in free space?
Both. But that's still only one relationship, because the wavelength and frequency are tightly related ... if you specify one, you've specified both.
What is the primary cause of signal loss in satellite communication?
Free Space Loss is the primary source of signal loss in satellites. As the signal propagates through the atmosphere it disperses. With normal terrestrial antennas, the distance is so short that this is rarely an issue. However, the great distances that satellites must communicate over make this a major problem for global space-based communication.
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.

Why the phase velocity in a waveguide can exceed the velocity of light?
Guide wavelength is defined as the distance between two equal phase planes along the waveguide. The guide wavelength is a function of operating wavelength (or frequency) and the lower cutoff wavelength, and is always longer than the wavelength would be in free-space. Here's the equation for guide wavelength:Guide wavelength is used when you design distributed structures in waveguide. For example, if you are making a PIN diode switch with two shunt diodes spaces 3/4 wavelength apart, use the 3/4 of a guide wavelength in your design. The guide wavelength in waveguide is longer than wavelength in free space. This isn't intuitive, it seems like the dielectric constant in waveguide must be less than unity for this to happen... don't think about this too hard you will get a headache. === ===
