Don’t waves need a medium to travel through? Isn’t space just essentially empty? I know they’re electromagnetic waves, but what does that mean essentially?
Edit: Thanks for the response guys. From your response I’ve realised there’s no way to explain to a 5 year old how light works!

Well if ocean waves move through water then wouldn’t light be the medium?
As Energy moves through water it creates waves or I guess you could say that water can behave as a wave too.
