Mirrors and Reﬂection
Students observe how ﬂat mirrors reﬂect light in straight lines and produce inverted images. They compare reﬂection of light by smooth and bumpy surfaces. Then they determine how the angle between two mirrors affects the number of images that they see reﬂected in the mirrors. Finally, they compare the images they see in convex and concave mirrors.
