Why does the ITU-R only regulate lower frequencies up to some hundred GHz and not higher frequencies in the THz range?

Because of their higher reach. And thus, military applications and others should be free to use them regardless of the country or region where they are transmitted. Higher frequencies have a much lower reach, since their wavelength is lower, and so there's sense in regulating them.
Besides, lower frequencies implies lower data transmission rates, and hence its lower importance as well, I'd say!

In twisted-pair wire how does the twist ratio affect transmission?
(1) the higher the twist, the higher the throughput (2) The higher the twist, the the lower the crosstalk
Why noise immmunity is more in integrator than differentiator?
noise is a ac signal(high frequency range), as LPF allows only lower frequencies integrator is has more noise immunity than differentiator
What are the advantages and disadvantages of mid range computer?
The advantage is lower purchase price. The disadvantage is that the computer has lower or mid-range specifications compared to a higher-end computer. A mid range is suitable for normal home computer use. A higher-specification is better for gaming.
Why the frequency of aeroplanes is 400 Hz?
Higher the fequency , higher the speed. Similarly,freq is inversely proportional to the the flux , higher the freq lower the flux requirement hence lower the winding req. which will reduce the weight ( this is necessary req. in operation of Aeroplane) of the winding The higher frequency allows a lighter transformer. Doubling the frequency allows the transformer's iron core to be half the weight. So 400 Hz allows light transformers (and motors) to be used.
What is the difference between frequency and pitch?
The human ear is capable of detecting sound at frequencies between about 20 and 20,000 Hz. Within this frequency range, however, the response of the ear is not uniform. The ear is most sensitive to frequencies between 200 and 4000 Hz, and its response decreases toward both higher and lower frequencies. There are wide variations in the frequency response of individuals. Some people cannot hear sounds above 8000 Hz, whereas a few people can hear sounds above 20,000 Hz. Furthermore, the hearing of most people deteriorates with age. The sensation of pitch is related to the frequency of the sound. The pitch increases with frequency. Thus, the frequency of middle C is 256 Hz, and the frequency of the A above is 440 Hz. There is, however, no simple mathematical relationship between pitch and frequency. frequency causes the different types of pitch

Why do we use high frequency waves as carrier waves?
The use of high frequencies for carrier waves in communications permits a higher rate of information transfer than could be accomplished with lower frequencies. The higher frequencies have the potential for higher "data density" or "information density" than lower frequencies.
How is the pitch of sound related to frequency?
Human auditory range is about 20 hz to 20khz, but can vary slightly from person to person. Lower frequencies are lower in pitch and higher frequencies are higher in pitch.
Do X-rays have lower frequencies than infra-red waves?
No. X-rays have much higher frequencies.
How do you change the pitch sound?
Adjust the wavelenght! The higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Basically, the longer the wavelength, the lower the pitch.
What is ossilloscope?
Basically, is a device which measures the amplitude and frequencies of a sound wave. It is shown on a screen. Closer waves, higher frequencies. Longer waves, lower frequencies.
Are the frequencies of radio and television signals higher or lower than those detected by the human eye?
Substantially lower.
Difference between coaxial cable and wave guide?
Waveguides are used at higher frequencies where their loss is lower than coaxial cable. Coaxial cable is used at lower frequencies where waveguides are too large and heavy. Lastly Coaxial cable is also used at higher frequencies where some flexibility is required.
Why is red red?
An object is red because it is absorbing the blue end of the visible spectrum (higher frequencies) and reflecting back the red (lower frequencies) to your eyes.

Why higher frequency greater than 60Hz cannot be used?
Frequencies higher than 60Hz are frequently used. Although there are radio waves lower than 60Hz, all of our radio transmissions are well above that. If you mean why frequencies for mains power supply above 60Hz can't be used, the answer is, they can. The higher the frequency though, the higher the loss although this doesn't really come into play until frequencies above several hundred Hz are used. 50Hz or 60Hz were chosen originally because of the mechanical nature or early generators.
