The second one is the Cathode-Ray Tube (CRT). A vacuum tube where electrons are accelerated and deflected to create images on a fluorescent screen. Once central to TVs and monitors, it was originally key to J. J. Thomson’s experiments that helped discover the electron!

The first one is the Photoelectric Effect! Einstein proposed that photons come in packets with a specific energy. If the energy is large enough, it can knock an electron loose. This discovery helped him win a Nobel prize and is now easily replicated across the globe.

Sounds good! Sent you a PM.

Oh I’m down to spar!
