Neon lamps are fun to play with. These old-school indicators were once heavily utilized in many types of equipment for indication purposes but now seem largely relegated to mains voltage indication ...

When light hits a material, electrons can be released from this material -- the photoelectric effect. Although this effect played a major role in the development of the quantum theory, it still holds ...

I took a deep dive into the photoelectric effect — where light hits a surface and kicks electrons out. It’s simple, mind-blowing, and totally changed how we understand energy and matter. Here’s how it ...

Photoelectric detection systems form an essential cornerstone of modern optical instrumentation. These systems capitalise on the photoelectric effect to convert incident light into electrical signals, ...
