Do waves with a shorter wavelengths travel faster than waves with longer wavelengths?
The physical length, short wavelengths are shorter than long wavelengthsThe frequency, short wavelengths are higher frequency than long wavelengthsThe energy per photon, short wavelengths have more energy per photon than long wavelengths
What frequency does H2O breakdown?
By this I mean is there a particular electrical pulse width or frequency that H2O breaks down?
If a wave's wave length increases what happens to its frequency?
It goes down. Wavelength is inversely proportional to the frequency
Why is it not possible to increase the wavelength and frequency at the same time?
Wavelength times frequency equals speed (of the wave). Therefore, unless you also change the speed, if wavelength goes up, frequency goes down, and vice versa.Wavelength times frequency equals speed (of the wave).

How are the frequency and the wavelength of a light wave related?
(Wavelength) x (frequency) = (wave speed) Wavelength = (speed) / (frequency) Frequency = (speed) / (wavelength) Note: This is true for any traveling wave, not only electromagnetic ones.
What are telecommunication links?
In satellite communication, up link refers to the signal traveling up to the satellite while down link refers to the signal coming from the satellite down to earth.
Why must a satellite have a distinct up link and down link frequencies?
These are frequencies used for satellite communications. Usually in the Gigahertz bands. Uplink is on a differenct channel to downlink, to avoid interferece. The Uplink, is the signal sent to the satellite, via a dish antenna, which focuses the signal in the direction of the satellite. On board the satellite, this signal is changed and re-transmitted, on a different frequency (Downlink), and beamed back to earth. This way huge distances can be covered on earth, despite the curvature and with minimal power.
Suppose a bug is jiggling up and down and swimming towards you at the same time compared to the frequency at which the bug is emitting waves the frequency of the wave reaching you is?
The frequency of the waves reaching you is higher then.
What the frequency of xxx channel on nilesat?
The FX channel frequency for nilesat is 102 (7.0 West), 12226 H down (Transponder 27), Symbol rate 27500, FEC 3/4. Nilesat is an Egyptian satellite communications company.
Chicony web camera doesn't work on toshiba satellite a350 on windows 7 64 bit need a solution?
please check out the frequency of both your camera n the up link n down link frequency used by the satellite. Answer: I don't how to do that but it was working perfectly and one day just stopped working so I think it is something else.
When was Down in the Shacks Where the Satellite Dishes Grow created?
Down in the Shacks Where the Satellite Dishes Grow was created in 1992.
What is the relationship between density and frequency?
Frequency is equal to inverse of the square root of density. As the frequency of a string for example goes up the density will go down but in a non-linear fashion. That is to create higher and higher frequencies less and less density decreases are required.
What is LNB?
The LNB (Low Noise Block Down-Converter) is part of the receive chain of yourVSAT. Located on the feed horn, the LNB converts the satellite signal that was reflected off of the satellite antenna’s reflector fromC-Bandinto anL-Band signal. The L-Band signal is in the frequency range of 950 to 1750 MHz and is considered more manageable. This is partially due to the fact that the transmission of the lower frequency signal can be more reliable when using a coaxial cable than is the case when higher frequency C-Band signals are transmitted of on this type of cable. Virtually all new satellite routers today use L-Band inputs. An LNB can be identified by its F-type output connector.BY AUQIB KHAN
What does the length of a string on a guitar have to do with pitch?
Vibrations run up and down the string at the sound of speed. The longer the string the lower the frequency of the wave biting both ends, resulting in a lower pitch. Frequency is simply the frequency of the vibrations.
What happens to the satellite if its life period is over?
i think it might shut down. if its a space satellite it will shut down and float away.
Why must a satellite have distinct up link and down link frequencies?
This is done to avoid crosstalk. If, for example the up and down -links were on the same frequency, it would work much like a walkie-talkie, meaning only one person could send, and one receive, at any given point in time. By giving each direction its own carrier wave, it allows both deviced to send and receive simultaneously, which greatly speeds communication.
How did the satellite fall down?
It lost its balance......
