Hello, I'm Raydann. An edit that you recently made to Photoelectric effect seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks!  ❯❯❯  Raydann  (Talk)   08:22, 14 November 2022 (UTC)
