A source of monochromatic light with wavelength lambda is located in point A which is p away from some lens. Virtual image of A is in point A'. Parallel to line AA' screen is D away from it (see fig.). Define lens type (converging or diverging), its focal length f, and derive the expression for estimating the order of the bright fringe that can be expected on the screen at point B. Assume D>>AA'.© BrainMass Inc. brainmass.com March 4, 2021, 7:06 pm ad1c9bdddf
Following is the text part of the solution. Please see the attached file for complete solution. Equations, diagrams, graphs and special characters will not appear correctly here.
From the above ray diagram, we can conclude that this is a converging lens. If it were a diverging lens, then the image A' would have been formed some ...
The solution is comprised of a step by step discussion on lens types and derivations for estimating the order of bright fringes.
