Increased wire or cable length causes the voltage to drop, this loss of charge is converted to heat and can cause electrical fires and damage to electronics.
because it is the fastest way to measure in very long distances for example earth to other far away planets

Americans did not feel connected to the whole country.
The right way
Telegraph cables- in use since l858 Cyrus Field the principal engineer involved.
Because it travels long distances and if you traveled long distances you would be tired so the light is absorbed by the surroundings

Yes but it's no the greatest conductor for long distances

Optical fibers can carry light long distances because of total internal reflection, which ensures that light stays within the fiber by continuously reflecting off the inner walls. This allows for minimal loss of signal strength over long distances, making optical fibers an efficient method for transmitting light.
AM travels well over longer distances than FM is capable of, but has a lower fidelity and is more susceptible to metal, which is why it is not used as often in cities.
Because wires are not perfect conductors, energy is released as heat. This is why electricity is transmitted at very high voltage and low current to reduce energy loss.
Electricity travels in a vacuum at aprox. 186,000 miles per second. Now do the math!
Light with wavelengths between 1300 nm and 1550 nm, known as infrared light, is commonly used for long-distance optical communication in fiber optic networks. This wavelength range offers low signal attenuation and dispersion, allowing signals to travel further without significant loss.
The moose travels by walking. The moose has very strong legs that are built to travel long distances in a short amount of time.
the signal goes out of sink due to refraction
