As a variation on yesterday's image, here is a more complete image of the visible spectrum of the sun, due to a diffraction grating taped to our window, and displayed on white paper on the floor of our house. For scale, shoes are shown at the bottom of the picture.

Equipment used: Canon EOS Rebel T5i with a standard zoom lens (EF-S 18-55 mm).
