👁✨ All eyes on the weekend! This video from @physicsfun gives us #thatFridayfeeling as he demos the Frensel Mirror Array in our "All Eyes On Me" exhibit! Happy #Friyay!! 😎⠀ ⠀ Repost: Fresnel Mirror Array @exploratorium : 360 mirrors arranged to reflect to a single focal point in this exhibit entitled “All Eyes on Me”. A mirror version of the Fresnel lens, where each concentric ring of mirrors is slanted toward the center, with the lager rings slanted more, such that the full assembly acts like a parabolic mirror.🌟With special thanks to the Exploratorium! ➡ Follow the link in my profile for more info and where to find many of the amazing items featured here on @physicsfun #physicsfun #physics #physicstoy #exploratorium #optics #fresnel #fresnellens #fresnelmirror #parabola #parabolicmirror #focalpoint #focus #science #scienceisawesome (at Exploratorium)
