PIRA 6A20.35 - Reflection from Curved Surfaces: Optic Mirage

---

Instructions / Notes:

• Two concave mirrors face each other.
• An image, in this case a pig, appears to be resting on a convex surface.
• The pig is used because it is made soft enough material so as to not scratch the mirror.
• The document camera or a lectern video camera can be used to capture the image.
• Shine a light so the reflection appear more 3 dimensional.
