File talk:Photon energy vs frequency.png

If anybody is reading this, is there anyway I can erase this file? The resolution is too low. I am wanting to replace it with one that has a higher resolution, but this requires a different file extension so I am unable to replace it.

Thanks! — Preceding unsigned comment added by Yen-Tzu (talk • contribs) 09:46, 28 July 2018 (UTC)
