I made several edits to a question about wavelengths. Each version of this question was marked as off-topic. Since I cannot post new question on the Physics site, I need to work on improving my existing questions by editing them to comply with the site's guidelines and address any feedback I have received. So, what improvement to the wavelength question will make it on-topic on the Physics site?
Even on the Spanish site, I had to make several edits to get an on-topic question.
UPDATE: "Stephen G" says:
it's arguably a question (even in the form I suggested) which is opinion based or which is a moving target (the extremes we can measure will change with technology as it improves). So it's a problem to answer this question beyond stating roughly what low and high wavelengths we can measure.
So, what question based on facts could I ask about wavelengths?
I have made several edits, but I am getting frustrated that the question is not getting reopened. One question on the English site took several edits before it finally reopened.
Now the question has finally reopened and I have two answers, still the question has 6 downvotes and 1 upvote. Why is the question still attracting downvotes?
