How do you appreciate the coincidence of the experimental facts with the results obtained by a ray diagram in terms of behaviour of images formed by lenses?

Answer»
  • Ray diagrams are very useful in optics. 
  • By the ray diagrams, we can easily find the values of image distance, object distance, focal length, radius of curvature, magnification, etc. 
  • These results are exactly equal to the result gotten by an experiment. 
  • For example : In the experiment, with a convex lens, we get clear image of an object, on a screen by adjusting the screen.

Then, we measure the image distance (v) practically. This takes more time and requires equipped lab also. 

But, by simply draw a ray diagram on a paper, we can get exact image distance (v) very easily, without lab. 

  • So, ray diagrams are very useful in the construction of microscopes, telescopes, etc. 
  • Hence, one can trust and depend on the result of ray diagrams instead of several lab experiments. 
  • So, I appreciate the ray diagrams.
