Question 2

How can we easily understand the image that results from a pinhole camera like the one shown here?
 a. The size and orientation of the image can be determined by examining the relative sizes of the sides of similar triangles that result from drawing light rays from parts of the object, through the pinhole and onto the rear of the camera.
  b. Maxwell's equations describing the behavior of light need to be applied.
  c. We need to use the lens equation that calculates where a camera lens forms images.
  d. The pinhole camera takes a picture of a pinhole-sized piece of an object.
  e. The pinhole eliminates the colored light rays, thus creating a black-and-white picture.
