Please visit the 3 mirror demos at the back of the room. PLEASE DO NOT TOUCH THE MIRROR SURFACES. Thanks much. CORNER MIRROR (on center pedestal): Find the 3 images (ignore the bottom mirror). The central image (in the corner) is double reversed, so that writing can be read normally. CONVEX SPHERICAL MIRROR (west side): Note that the image is upright and virtual and gets smaller as you retreat. CONCAVE SPHERCIAL MIRROR (east side): The location of the focal point (F) and of the center of curvature (C) are marked on the floor. Use your hand as an object; when your hand is inside the focal point, you should observe an upright virtual image; it gets smaller as the object moves towards the mirror. When your hand is outside the focal point, the image is real and inverted; its get smaller as the object moves away from the mirror. Confirm the reality of the image for objects outside the focal point by placing a white card at a distance of about 20 cm outside the focal point. You should be able to see an image of the bright lamp on the mirror side of the card.
