Mirrors

A mirror reflects light in a way that preserves the original image. They are different from other materials that reflect due to the fact that they do not preserve the original waves. Mirrors used most often have a flat surface where the reflect is perfectly symmetrical. Curves mirrors will produce magnified images that distort the reflected images. Mirrors are used everyday for personal use, decoration and architecture. Mirrors are also used in devices such as telescopes, lasers, cameras and industrial machinery. Most mirrors are designed for visible light.

Looking in a mirror, the image will be reversed from the original image.  A mirror will reverse the image on the forward and backward axis. Left and right will be defined relative to the front and back of the image. Flipping the image front and back and left and right is equivalent to a rotation halfway around the vertical axis.

Statistics of the Criminal Justice System and how they represent a larger role of bias and unequal treatment of minorities in general is discussed in the solution focusing primarily on the disproportionate rate of African Americans incarcerated.

Demographic data such as race, age, gender, and social class are associated with crime and criminal justice and can be illustrative of a larger picture in terms of social justice. For example, the racial composition of inmates in U.S. prisons can be illustrative of larger issues dealing with society, police, and the courts. Thes

Are Wing Mirrors Flat, Convex or Concave?

Determining Characteristics of an Image: Mirror Example Problem

The problem below is similar to the problems in chapter 25 & 26 in the Cutnell and Johnson College Physics book so it should be solved in a similar fashion. This is physics-II WITHOUT calculus: You are given a concave mirror with focal length 40.0cm. You start with an object 50.0cm high at 160cm in front of the mirror.

Simple Harmonic Motion and Period Oscillations

Name three example of objects from eveyday life that exhibit Simple Harmonic Motion and estimate the period of the oscillations. if the period changes under certain conditions, discuss what parameters of the object affect the period and how they do so ?

Parallel rays on a plane mirror

A plane mirror is placed in front of a multiple ray projector so that the central ray is back upon itself. The other rays are adjusted so they are also reflected back on themselves. In this way, all 5 rays are parallel. A concave mirror is placed in the path of the rays so that the central ray is again reflected back upon

Angle of Incidence and Reflection of Plane Mirrors

Two plane mirrors, M1 and M2, are placed together as illustrated in the figure (see attachment). a. If the angle between the mirrors is 70o and the angle of incidence of a light ray incident on M1 is 35o, what is the angle of reflection from M2? b. If the angle between the mirrors is 115o and the angle of incidence of a ligh

Two people stand 3.0 m away from a large plane mirror and are 5.0 m apart from each other in a dark room. At what angle of incidence should one of them shine a flashlight on the mirror so that the reflected beam strikes the other person at the same height that the flashlight is held? Assume the person with the flashlight holds i
