What technology is used to collect electromagnetic radiation and convert it into an image?

The correct technology for collecting electromagnetic radiation and converting it into an image is a camera. Cameras are designed to capture light, which is a form of electromagnetic radiation, and produce a visual representation of what is being observed. They work by using lenses to focus the light onto a sensor or film, allowing the details of the scene to be recorded and reproduced as an image.

While telescopes also collect electromagnetic radiation, their primary purpose is to magnify distant celestial objects rather than to directly create images like a camera does. Similarly, microscopes are used to observe small objects, typically at a very close range, and they provide a magnified view rather than focusing specifically on the conversion of electromagnetic radiation to images in a broad context. Spectrometers, on the other hand, analyze the spectrum of electromagnetic radiation rather than creating images from them.
