Because you use light to communicate in sign language, and light is just an electromagnetic wave like radio but on another frequency. You just need to be in line of sight

Really, radio communication is about creating and transmitting those radio waves. Sign language relies on reflected light waves so it’s actually a form of RADAR 😀

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct
