continuous variable for [Watts] means that it can be any value,

or is there some quantum mechanical rule of light that it is discrete, idk

Answer 4

Answer 5

`or is there some quantum mechanical rule of light that it is discrete`

I think you're overthinking things @DanJS

I think it's simply continuous because you can have 100 W or 101 W or anything in between (100.5 W or 100.005 W and so on)

Answer 6

yes i assumed continuous, but not sure
