Hello, I'm Ale jrb. I wanted to let you know that I reverted one of your recent contributions—specifically this edit to Huygens–Fresnel principle—because it did not appear constructive. If you would like to experiment, please use the sandbox. If you have any questions, you can ask for assistance at the Help desk. Thanks. A le_Jrb talk 16:37, 10 June 2021 (UTC)
