When modulation frequency is doubled modulation index also doubled in case of FM or pm or am?
In Frequency Modulation (FM), if the modulation frequency is doubled, the modulation index does not necessarily double; it depends on the amplitude of the modulating signal. In Amplitude Modulation (AM), the modulation index is defined as the ratio of the peak amplitude of the modulating signal to the carrier amplitude, so it remains unchanged with varying modulation frequency. For Phase Modulation (PM), similar to FM, the modulation index is influenced by the amplitude of the modulating signal and does not inherently double with the modulation frequency. Thus, modulation frequency and modulation index are not directly linked in this way for FM, PM, or AM.
When modulation frequency is doubled the modulation index is halved and the modulating voltage remains constant the modulation system is?
the modulation system is of FM
In which Analog to analog modulation methods does the peak amplitude?
Frequency modulation Phase modulation
How does quadrature amplitude modulation works?
QAM is a combination of phase modulation & amplitude modulation.

Why a high percentage of modulation is desirable?
Is important to use as high a percentage modulation as possible while ensuring that overmodulation does not occur. The side bands contain the information and have maximum power at 100% modulation. And AM transmiters attempt to maintain betwen 90 and 95 percent modulation as a compromise between efficiency and the change of drifting into into overmodulation. sources page 76 second paragraph of the MODERN ELECTRONIC COMUNICATION By Jeffrey S.Beasley and Gary M.Miller
Why is it desirable to have the modulation index of an AM signal as large as possible without overmodulating?
It uses the maximum power available to the transmitter and makes the signal more readable at a greater distance.

How velocity modulation and density modulation related to each other?
due to velocity modulation density modulation occurs in TWT
How communication produce?
This is a highly technical subject. It is not possible, or desirable, to fully explain it here. Basically electromagnetic waves of the appropriate frequency are generated, these are then manipulated (called modulation) in various ways to carry information.
