I. IntroductionThe Purpose of this report is to understand how images are formed

differently in a plane, a concave, and a convex mirror which the changes in

image at different object distances are observed. A Light ray diagramcorresponding to each case is also constructed to confirm this behavior. The

magnification of the concave and convex mirrors are also computed using the

light ray sketches.

Subtopics

The law of reflection - hen a ray of light strikes a plane mirror, the light

ray reflects off the mirror. !eflection involves a change in direction of the

light ray. Image formation for plane mirrors " As a person sights in a mirror at the

image of an object, there will be reflected rays of light coming from the

mirror to that person#s eye.

Converging " is a type of lens that converge the beams of light from a source. The

focal length is positive, and the image is always real and inverted, except

for p$f when the image is virtual and the same way up.

  Diverging - is a type of lens that diverge the beams of light from a source. The focal

length is negative, and the image is always upright, virtual, and diminished

in si%e &'$(). Virtual image * the image formed when light only appears to come from a

location of the image. Real image * image formed by convergence of light.

S"mmar$ of the Report+pherical mirrors have curved surfaces similar to the sections of a

sphere hence the name. owever, there are two types of spherical mirrorsthe -onvex mirror, which has its reflective surface at the outer half of asphere, and the -oncave mirror, which has its reflective surface at the inner half of a sphere. The curved surfaces of these two mirrors affect theformation of the images. -oncave mirrors tend to produce converging,inverted, real images in front of the mirror. hile -onvex mirrors tend toproduce diverging, upright, virtual images behind the mirror. Although their resultant images may vary due to difference in focal points, focal lengths

and position of the object.

There are two types of images formed by spherical mirrors irtual

and !eal images. A real image is an image formed by actual rays of light.

!eal images are always inverted, and they may be either larger or smaller 

than the object. Virtual images are images, such as that seen in a mirror,

in which the rays of light appear to be emanating from some object that

isn/t there is called a virtual image. irtual images are always erect. They,

also, may be either larger or smaller than the object.

 

The images formed are also differ based on the behavior of the light

affected by the lenses. 0oth converging lenses and diverging lenses are

very important in the understanding of optics and other related fields.

-onverging lens converge light beams from a source whereas diverging

lenses diverge light rays from a source.

To be able to distinguish the images formed we use the mirror e1uation to determine the approximate location and si%e of the image,although it will not provide numerical information about image distance andobject si%e.
