appear to diverge from it after passing through a concave lens. The focal length‚ f of a lens is the distance between the focal point and the optical centre of the lens. For a convex lens‚ the ticker the lens is at the centre‚ the shorter is the focal length of the lens. For a concave lens‚ the thinner the lens is at the centre‚ the shorter is the focal length of the lens. Objective: To determine the focal length of a convex lens. Theory From the lens formula‚ 1 = 1 + 1

Spherical Mirrors A spherical mirror is a mirror which has the shape of a piece cut out of a spherical surface. There are two types of spherical mirrors: concave‚ and convex. These are illustrated in Fig. 68. The most commonly occurring examples of concave mirrors are shaving mirrors and makeup mirrors. As is well-known‚ these types of mirrors magnify objects placed close to them. The most commonly occurring examples of convex mirrors are the passenger-side wing mirrors of cars. These type of mirrors

Should Merloni replace its network of regional warehouses with transit points? To focus your thoughts‚ consider the RDC’s at Roma and Catanzaro. Which of these RDCs would you replace this with a transit-point system? Why? When evaluating whether Merloni should transition from its regional distribution centers (RDCs) to a transit-point system / cross-docking system‚ there are several factors to consider: 1. Industry and type of product 2. Customer demands and service levels 3. Location of the

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

Mise en scene Analysis: Days of Being Wild After viewing the opening sequence of Days of Being Wild for the first time‚ several things were apparent. We have two main characters that are involved in an ongoing exchange. It begins as a simple transaction leads to our first insight into whom these characters are. Our leading man is confident. He seems to know what he wants and doesn’t appear to take no for an answer. The girl he’s after seems reserved and seems to decline his advances despite
