Sound waves are not detected by telescopes, as telescopes are instruments that are designed to detect electromagnetic radiation, such as radio waves, X rays, and visible light. Sound waves require a medium, such as air or water, to travel through, and can't propagate through the vacuum of space where telescopes operate.

Reflective and Radio telescopes gather radiation at different parts of the electromagnetic spectrum that they operate, visible light for the optical telescope and Radio frequencies for the Radio telescope. But in both cases, it's electromagnetic radiation. Radio telescopes have to capture the incoming energy that's needed to be above a certain noise and gets processed in electronic circuitry. The result is plotted out as picture of which each point indicates the location at which the beam of the antenna is pointed. It has a huge dish to reflect the incoming energy like that in a reflector telescope. The same terminology can be used in reflecting telescope, but the processing is done in a CCD camera positioned at the focus of the telescope.
Radio telescopes and infra-red telescopes operate at longer wavelengths/lower frequencies than visible light. Ultraviolet telescopes operate at shorter wavelengths/higher frequencies than visible light.
Sensors that primarily operate in the electromagnetic spectrum just below the range of visible light include infrared (IR) sensors. These sensors detect and measure infrared radiation, which has longer wavelengths than visible light. They are commonly used in applications such as night vision devices, remote temperature sensing, and proximity detection.
As far as I know, there is no "optical radio telescope". There are, separately, optical telescopes (which work with visible light), and radio telescopes (which work with radio waves).
Radio signals are sent from Earth, to operate the telescopes.

Microwave ovens use electromagnetic radiation in the microwave region of the electromagnetic spectrum. Specifically, they typically operate at a frequency of 2.45 GHz, which corresponds to a wavelength of around 12 cm.

There are no such things as 'AM' and 'FM' waves. When we take an electromagnetic wave, and force it to carry information by changing its amplitude according to some pattern related to the information, we operate on it with the process of 'AM'. Commercial radio stations that add sound information to their carrier waves in that way operate in the frequency band of 0.55 - 1.7 MHz (in the US). When we take an electromagnetic wave, and force it to carry information by changing its frequency according to some pattern related to the information, we operate on it with the process of 'FM'. Commercial radio stations that add sound and other information to their carrier waves in that way operate in the frequency band of 88 - 108 MHz (in the US).

The electromagnetic spectrum affects the transmission of wifi signals by providing the range of frequencies that wifi signals can use to travel through the air. Wifi signals operate within specific frequency bands within the electromagnetic spectrum, allowing them to be transmitted wirelessly from routers to devices like smartphones and laptops. The different frequencies within the spectrum can impact the speed, range, and reliability of wifi signals, with higher frequencies typically offering faster speeds but shorter ranges, and lower frequencies providing better coverage but slower speeds.
Some devices that involve electromagnetic waves that we can't see include microwave ovens (use microwaves), X-ray machines (use X-rays), and radio transmitters (use radio waves). These devices operate on different parts of the electromagnetic spectrum, beyond what is visible to the human eye.
