Mara draws the ray diagram shown. From left, a large flag above a line running through a left focal point then the center of a thin double convex lens then a right focal point, the a small flag below the line. A line from the top of the flag runs straight through the top half of the lens to a label 2 at right. A line running from the top of the large flag goes through the center of the lens to the top of the small flag. A line running from the top of the large flag goes through the left focal point to the center of the bottom half of the lens and the straight to the top of the smaller flag. Which describes Amara’s mistake? She should have drawn a concave lens instead of a convex lens. She should have drawn the image right-side up instead of upside down. Ray 2 should cross through the focal point on the right side of the lens. Ray 3 should point at a downward angle after passing through the lens.
