Analog signals primarily travel over telephone lines.
Telephone lines are designed to transmit analog signals, which are continuous waveforms representing voice or audio data. These analog signals are converted from the human voice by analog microphones and then sent over the telephone network. The telephone network, historically comprised of copper wires, was optimized for analog signal transmission.
Analog signals are characterized by their ability to convey a wide range of frequencies, allowing them to carry voice and other audio signals effectively. When you speak into a telephone, your voice is converted into analog electrical signals, which are then transmitted to the receiving end. At the receiving end, these analog signals are converted back into sound waves for the recipient to hear.
It's worth noting that modern telephone networks, especially in developed countries, have largely transitioned to digital transmission using technologies like Voice over IP (VoIP). In these cases, your voice is digitized into binary data packets for transmission over the internet. However, even in these digital systems, the initial conversion from voice to digital format often occurs at the analog-to-digital interface in your device, such as a microphone or cell phone.

Visual is something that an individual can see with his/her two eyes. Where as ultraviolet Ultraviolet is electromagnetic emission with a wavelength from 10 nm to 400 nm, lower than that of apparent light but greater than X-rays. UV radiation is already in sunlight composing about 10% of the entire light amount of the Sun.
