An object of height 3 cm is placed at a distance of 25 cm in front of a converging lens of focal length 20 cm, to be referred to as the first lens. Behind the lens there is another converging lens of focal length 20 cm placed 10 cm from the first lens. There is a concave mirror of focal length 15 cm placed 50 cm from the second lens. (b) Most simple telescopes have two convex lenses. The objective forms a case 1 image that is the object for the eyepiece. The eyepiece forms a case 2 final image that is magnified. The most common two-lens telescope, like the simple microscope, uses two convex lenses and is shown in [link] (b). How to turn on camera and microphone on hp laptopOptics is the cornerstone of photonics systems and applications. In this module, you will learn about one of the two main divisions of basic optics—geometrical (ray) optics. In the module to follow, you will learn about the other—physical (wave) optics. An aperture of a mirror or lens is a point from which the reflection of light actually happens. It also gives the size of the mirror. f. Principal Focus : Principal Focus can also be called as Focal Point. It’s on the axis of a mirror or lens wherein rays of light parallel to the axis converge or appear to converge after reflection or refraction. Principal Focus is also what determines the Focal Length of the mirror.

Ray Diagrams for Lenses. The image formed by a single lens can be located and sized with three principal rays. Examples are given for converging and diverging lenses and for the cases where the object is inside and outside the principal focal length. The "three principal rays" which are used for visualizing the image location and size are:

The difference between mirror and lens is that mirror means a smooth and highly polished glass surface, through which images are formed by reflection, as the light falls on it. On the other extreme, a lens is a part of transparent refracting medium, (i.e. glass), bounded by two surfaces, of which atleast one is buldged. The equation I know is the same for both mirrors and thin lenses, namely 1/v + 1/u = 1/f where u =object distance from the mirror/lens v =image distance from the mirror/lens f =focal length of the mirror /lens Now u and v are distances from the object and image to the lens on the side where "light has every business being".

The image height vs. object distance curve is exactly the same as those of mirrors (convex lenses the same as concave mirrors, concave lenses the same as convex mirrors). Refer to above. converging and diverging lenses, focal length Focal length for converging lens is positive. Converging lens is convex.

Physics Mirrors. Jonathan is a published author and recently completed a book on physics and applied mathematics. Physics mirrors are where light can be reflected and reconvened to form images. Two different types of mirror are concave and convex mirror with different properties. Two types of image formed by mirrors are real image and virtual image.
