what does 'rough analogy' mean?(uppercase part below)
"As light travels through space it decays or grows dimmer with distance. Think of a firework bursting in the night sky. When the firework first bursts the sparks are bunched close to each other. Over a short period of time they quickly spread out from each other. If you replace sparks with photons of light and the firework with your light source than you have a very ROUGH ANALOGY to how and why light decays. "

An analogy is something that explains a concept by comparing it to something else. In this situation, the writer is helping you understand how/why light decays by comparing it to fireworks. A “rough analogy” just means that the analogy (comparison) is not perfect, because this concept is difficult, but it should help you understand a little bit better. I hope this helps!
