Do frequencies in the 28 GHz spectrum have 40x the capacity of frequencies in the 700 MHz spectrum all other things being equal?

The answer is no. What determines maximum channel capacity is spectrum width not absolute value. For example 700 - 720 MHz would have the same potential capacity as 28000 to 28,020 Mhz. 28,000 to 28,160 Mhz could potentially have 40 times. 700 Mhz is much better spectrum than 28 GHz because lower frequencies have lower attenuation rates and travel further with acceptable signal to noise ratio. Lower frequencies are also much better going through walls. That's why Verizon and others paid so much for it.

What does an audio spectrum analyzer do?
An audio spectrum analyzer gives a live view of the intensity of the spectrum. Using either a line graph or a bar graph and a display it will show you how loud certain frequencies are at any given moment of the audio that is being fed to it.
A frequency of 1GHz on a spectrum analyser corresponds to what frequency in the Ku band?
The Ku band of microwave frequencies ranges from 12 to 18 GHz. A frequency of 1GHz is not in the Ku band. There is no correspondence. Is the 1GHz setting on the spectrum analyzer a center frequency? Or is it one of the ends of the spectrum analyzed? Is it the width of the spectrum being analyzed? And if it is the latter, what is its center? Knowing these things will still not change the answer given, but may help to "sort out" a possible problem with the question the way it is written.
What is in spectrum?
Wireless communications make use of the radio portion of the electromagnetic spectrum. Simply put, telecom operators send and receive signals at various frequencies to enable communication. This radio spectrum contains only a limited number of frequencies. Signals can be sent on different frequencies all at the same time, however, if frequencies are the same or too close they can interfere with each other. As the number of frequencies is limited, they need to be allocated to different service providers. Therefore, spectrum is allocated for various communication purposes world-wide. Is spectrum being given free to telecom operators? Contrary to popular perception, spectrum is not available for free. Currently, spectrum charge has two components - the entry fee charged is inclusive of one-time spectrum charge, and an annual spectrum charge based on a percentage of the Adjusted Gross Revenue (AGR) of the telecom company. The percentage of annual spectrum charges for GSM operators, for instance, varies with spectrum usage. Currently, the ceiling for annual spectrum charge is 6% of AGR. Trai, though, has recommended that the ceiling be lowered to 4%. Now, Trai's recommendations only say that there will be no one-time spectrum charge for allocation of IMT-2000 spectrum (meant for 3G) for existing service providers. The regulator has explained that the allocation to the existing operators should be viewed as extension of 2G spectrum allocations. However, a contrary view is that spectrum is a scarce resource and that additional allocation should be priced. Regards, Kanak New Delhi

What human organ is sensitive to a small portion of the electromagnetic spectrum?

What is population at equilibrium in science?
If something is said to be in equilbrium it means that is in its optimum environment and that it is functioning as efficently as possible. All the things that an organism needs are being met yet all the things that organism doesn't need are not being met. So a balance is produced meaning that the organism can thrive.
What is the electromagnetic spectrum.?
The electromagnetic (EM) spectrum is the entire range of frequencies that electromagnetic radiation can have. The EM spectrum is divided into sections based on the common characteristics that certain frequency ranges have. These sections are, in order from low to high frequency, radio waves, microwaves, infrared waves, visible light (which from low to high frequency is further divided into red, orange, yellow, green, blue, indigo, and violet), ultraviolet waves, X-rays, and gamma rays. You can think of the EM spectrum as an invisible rainbow with visible light being a small part of it. And, like a rainbow, the edges of the divided sections are blurry; i.e. there is no exact frequency where one can say, for example, that this wave is no longer an X-ray, but is instead a gamma ray. it is waves of light in order of their wavelengths and frequencies APEX: A chart of frequencies of light waves.
How can you Distinguish absorption spectrum from emission spectrum?
Emission spectra are bright-line spectra, absorption spectra are dark-line spectra. That is: an emission spectrum is a series of bright lines on a dark background. An absorption spectrum is a series of dark lines on a normal spectrum (rainbow) background.

What is the range of electromagnetic force?
Empirically speaking, it is the Hubble Limit. According to established theory, it is indefinite. I'm leaning toward the Hubble Limit being the right answer
What do the colors in a line spectrum represent?
Colors in a spectrum represent different frequencies of light. Light is formed when a particular atom or molecule is stimulated by some energy input - the energy forces an electron to jump to a higher level of excitation. When the electron falls back to its normal state it releases that energy as a photon of light, one that has a particular frequency determined by the atom or molecule and the amount of energy that the electron absorbed. So, when looking at a line spectrum (of, say, the light from a distant star) the color lines show the particular wavelengths of light that the star is giving off, which tell scientists a lot about what elements and compounds are in the star.
How does a flame test work is it something to do with the electron arrangement and orbitals in the atom being tested?
as the energy is converted to the particles, based on density of the particles they vibrate at different frequencies, these frequencys cause waves and they are situated in the visible spectrum, thus allowing you to see light of certain colour depending on the element at hand.
