MATERIAL REQUIRED Concave Mirror, Optical Bench THEORY A concave mirror is a spherical mirror with a reflective surface that curves inward, resembling the interior of a bowl or a cave. It is also known as a converging mirror because it causes parallel light rays to converge at a single point called the focus after reflecting […]
