Minor edits and secondary sources
Thank you for your contributions. Please mark your edits, such as your recent edits to Electromagnetic radiation, as "minor" only if they are minor edits. In accordance with Help:Minor edit, a minor edit is one that the editor believes requires no review and could never be the subject of a dispute. Minor edits consist of things such as typographical corrections, formatting changes or rearrangement of text without modification of content. Additionally, the reversion of clear-cut vandalism and test edits may be labeled "minor". Thank you. - DVdm (talk) 14:23, 24 October 2019 (UTC)

Note: I also have undone your edit, because it does not bring much to the article, and the source is a so-called wp:primary source anyway. Wikipedia needs wp:secondary sources. You can leave a comment on the article page, perhaps suggesting to add something from the source, if you like. Cheers. - DVdm (talk) 14:23, 24 October 2019 (UTC)
