Homework Help: Pinhole Camera

  1. Nov 22, 2011 #1
    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.
