Cathode ray and Photoelectric effect

Postby Jielena_Bragasin2G » Sat Oct 12, 2019 7:35 pm

Hi all! I am slightly confused between the Cathode ray and Photoelectric effect; I am wondering if they are in any way similar or related and if so how. Thank you!

Thomson found electrons through the cathode ray experiment because he was able to show that the cathode rays were negatively charged. In other words, cathode rays are basically electron beams and electrons are related to the photoelectric effect because in the photoelectric effect electrons are ejected.
