reflectors on the webcam

should be in electronic sites; EEVBlog, allaboutcircuit, etc instead

Imho simply depends on aerospace condition ie. zonal climate and weather

EM waves can be affected by atmospheric conditions, such as rain, fog, and snow. These conditions can cause radio waves to scatter or absorb, which can lead to communication disruption

cheated chatgpt:

Satellites use various wavelengths of electromagnetic radiation to perform their jobs, depending on the specific purpose of the satellite. Here are some examples of satellite applications and the corresponding wavelength ranges they typically operate in:

Communications satellites: These satellites use microwave frequencies, typically in the range of 1 to 50 GHz. This allows them to transmit and receive signals over long distances and through the Earth's atmosphere.

Earth observation satellites: These satellites use a range of wavelengths, from visible light to microwave and radio frequencies. Visible and near-infrared wavelengths are used for imaging the Earth's surface, while microwave and radio frequencies can penetrate clouds and vegetation to provide information on things like soil moisture and ocean surface temperature.

Weather satellites: These satellites use a range of wavelengths to observe different features of the atmosphere, including visible and infrared for cloud imaging, microwave for temperature and moisture profiling, and radio frequencies for communication with ground stations and other satellites.

Navigation satellites: These satellites use radio waves in the microwave frequency range, typically around 1.2 to 1.6 GHz, to provide precise location information to users on the ground.

Proportion of wavelengths used by satellites depends on the specific mission and application of the satellite

troubleshoot what ?

Without knowing what is your current level it is very difficult to suggest any book.

If you are talking about textbooks, it really depends on what topic you want to learn (Algebra, Calculus, Mechanics, Electromagnetism…).

If you want a generalist one, many colleges' choice has proven it's:

Physics for Scientists and Engineers

(the latest Edition is better of course) by Paul A. Tipler (Author), Gene Mosca

Conceptual Physics by Hewitt

Who says only on this

every code language/syntax is so hard for one, the person who's not the author, to understand it

unless it's provided with excellent comments and documentations

First case 5 years ago: https://www.truthorfiction.com/did-four-artificially-intelli...

remember few vaguely, there's another one-two but cannot really recall

not wrong as c++ libr, math.h etc, specs defines its functions' specs along with limitations

Do you still use Windows OS & software?

Linux multitude more immune, use it

no change

for long time ago and future

A special secure serene place

that's why library has such the special room of which some great scientist, inventor came out by its merit

cause database domain/science are upon the same loc.: US

Put it simple AI outright relies on database domain, data science

more explanation how such need or situation arose ?

Every Linux has

Dig in on each of their home/official site e.g: https://www.gnu.org/software/grub/manual/grub/grub.pdf

most say Gentoo or Funtoo (its improvement) excel in docs. among them
