Short Note

Observe the given figure and answer the following questions.

  1. Where is the above type of lens construction used?
  2. What type of image is formed by an objective lens?
  3. What happens instead of placing at Fo if the object is placed in between O and Fo?

Solution

  1. The above type of lens construction is used in a compound microscope.
  2. The image formed by the objective is real, inverted, and formed at a distance within the focal length of the eyepiece.
  3. If the object is placed in between O and Fo, a virtual image will be formed on the same side of the objective as that of the object. As a result, compound microscope will not be able to operate as expected.
Concept: Convex Lens

(c) What happen when he moves the object very close to the lens?

A student did an experiment with a convex lens. He put an object at different distances 25 cm, 30 cm, 40 cm, 60 cm and 120 cm from the lens. In each case he measured the distance of the image from the lens. His results were 100 cm, 24 cm, 60 cm, 30 cm and 40 cm, respectively. Unfortunately his results are written in wrong order.  

Rewrite the image distances in the correct order.
