Finding Images of a Red Ball at Point A: Location & Number

Click For Summary
SUMMARY

The discussion centers on determining the number of images of a red ball located at point A, specifically at coordinates (-1, -2), as seen by an observer at point O. The consensus is that the observer sees three images of the red ball. The locations of these images need to be expressed as ordered pairs (x, y) in meters, with the coordinate system defined by the corner of the mirror as the origin, where the +x axis extends to the right and the +y axis extends upward.

PREREQUISITES
  • Understanding of coordinate geometry
  • Familiarity with reflection principles in optics
  • Knowledge of ordered pairs and Cartesian coordinates
  • Basic problem-solving skills in physics
NEXT STEPS
  • Research the principles of image formation in mirrors
  • Learn about the laws of reflection and their applications
  • Study coordinate transformations in two-dimensional space
  • Explore practical examples of optics problems involving multiple images
USEFUL FOR

Students studying optics, physics educators, and anyone interested in understanding image formation through mirrors and coordinate geometry.

Homework Statement


A red ball is placed at point A in the figure. (Intro 1 figure) : figure attached

How many images are seen by an observer at point O?

Where is each image seen by an observer located?
Enter your answers as an ordered pairs (x, y) separated with comma(s), where x and y are in meters. Assume the origin is at the corner of the mirror, +x axis is directed to the right, and +y axis is directed upward.

Hi rayhan619! :wink:

Well, the object is at (-1,-2), so the three images are at … ? :smile:
