Controlled assessment research Focus length of a lens- The most important characteristic of a lens is its principal focal length‚ or its inverse which is called the lens strength or lens "power". Optometrists usually prescribe corrective lenses in terms of the lens power in diopters. The lens power is the inverse of the focal length in meters: the physical unit for lens power is 1/meter which is called diopter Convex- The word convex means curving out or bulging outward‚ as opposed to concave

MIRROR -The simplest and the most common optical instrument. -Uses the Law of Reflection to redirect light it receives. -It reflects most of the light in one direction. -Good reflecting mirrors can have 85% reflectance. Types of Mirror 1. Plane Mirror A mirror with a flat surface. Image formed: Laterally inverted Upright and always the same size as the object they reflect. Virtual image (images appear to behind the mirror) at the same distance as the object in front of the mirror. Examples:
