Answer 1

Answer:

The Anatomy of a Curved Mirror

Reflection of Light and Image Formation

Two Rules of Reflection for Concave Mirrors

Ray Diagrams - Concave Mirrors

Image Characteristics for Concave Mirrors

Mirror Equation

Spherical Aberration

Ray diagrams can be used to determine the image location, size, orientation and type of image formed of objects when placed at a given location in front of a concave mirror. The use of these diagrams was demonstrated earlier in Lesson 3. Ray diagrams provide useful information about object-image relationships, yet fail to provide the information in a quantitative form. While a ray diagram may help one determine the approximate location and size of the image, it will not provide wish to solve for.

The +/- Sign Conventions

The sign conventions for the given quantities in the mirror equation and magnification equations are as follows:

f is + if the mirror is a concave mirror

f is - if the mirror is a convex mirror

di is + if the image is a real image and located on the object's side of the mirror.

di is - if the image is a virtual image and located behind the mirror.

hi is + if the image is an upright image (and therefore, also virtual)

hi is - if the image an inverted image (and therefore, also real)
