SUMMARY

The discussion focuses on calculating the height of an object using a pinhole camera setup. Given an object located 100 meters away, with the image height measuring 5 cm on a screen positioned 10 cm from the pinhole, the height of the object can be determined using the principles of similar triangles. Participants emphasize the necessity of drawing a diagram to visualize the relationship between the object, image, and pinhole for accurate calculations.

PREREQUISITES
  • Understanding of pinhole camera principles
  • Knowledge of similar triangles in geometry
  • Ability to interpret ray diagrams
  • Basic skills in mathematical calculations involving ratios
NEXT STEPS
  • Research the principles of similar triangles in geometry
  • Learn how to create and interpret ray diagrams for optical systems
  • Explore the mathematical formulas used in pinhole camera calculations
  • Study the effects of distance on image size in pinhole cameras
USEFUL FOR

Students in physics or photography, educators teaching optics, and anyone interested in understanding the mechanics of pinhole cameras and image formation.

I don't have any idea how to go about this...
Please help!:frown:

A pinhole camera produces an image of an object kept at a distance of 100m from the pin hole. If the screen is 10 cm from the pin hole and the image is 5 cm high, what is the height of the object

Any help will be appreciated :smile:

Thank You!

Draw the diagram and similar triangles will give you the answer.

There is no diagram attached to the question :rolleyes:
 
Try the web for a diagram.
