Geometric Optics

A: Single Convex Lens

  1. Under what conditions is the magnification less than one, greater than one?

  2. What is the image distance when the object distance is twice the focal length? What is the magnification?

  3. Using the thin lens formula, explain why 1/(vertical intercept) is (or should be) the focal length of the lens?

B: Lens Combination

  1. Is the final image inverted or upright?

  2. What happens to the virtual image as you move the eyepiece further from and closer to the objective’s image?

When an object is placed at a distance greater than the focal length but less than twice the focal length from a convex lense
When an object is placed at a distance greater than the focal length but less than twice the focal length from a convex lense the image is diminished.the image is virtual.All of the other choices are not correct.the image is inverted.the image is formed on the same side as theobject.For an object placed in front of a concave lense,the image is always realthe image may be erect or inverted.the image is formed on the other side of thelense.the image may be...

Under normal market conditions, if your profits are greater than your average total costs, it is called making a profit and new firms try to enter the industry and existing firms expand. If your profits are lower than your average total costs, firms operate at a loss, and often exit the industry or contract. If your profit matches your average total cost, it is called breaking even and most firms operate at their current capacity. However, not all industries are...
