How to find intensity in double slit

Click For Summary
SUMMARY

The discussion focuses on calculating the intensity of light in a double slit experiment, specifically for orders m=0 to m=6, with slits measuring 0.140mm in width and a center-to-center distance of 0.840mm. Participants reference the intensity equations I/I0 = (E/E0)^2 and I = 4A0^2sin^2(beta)/(beta^2cos^2(gamma)). However, there is confusion regarding the determination of the variables beta and gamma, which are essential for solving the problem. The original poster expresses difficulty in locating the appropriate methods in their optics textbook.

PREREQUISITES
  • Understanding of wave optics principles
  • Familiarity with the double slit experiment
  • Knowledge of intensity equations in wave mechanics
  • Ability to interpret variables in mathematical equations
NEXT STEPS
  • Research the derivation of the intensity formula for double slit interference
  • Study the concepts of beta and gamma in wave optics
  • Explore the use of MATLAB or Python for simulating double slit experiments
  • Review advanced optics textbooks focusing on interference patterns
USEFUL FOR

Students in physics, particularly those studying optics, educators teaching wave mechanics, and anyone interested in the mathematical modeling of light interference patterns.

1. Homework Statement
the two slit of a double slit each have a width of 0.140mm and a distance between centers of 0.840mm. what the approximate intensity of orders m=o to m=6?

2. Homework Equations
i want to use the I/Io = (E/Eo)^2 but some book use
I = 4Ao^2sin^2 beta/beta^2cos^2gamma. i also don't know how to find the value for beta and gamma.

anybody please help me...

I'm sorry, I even went to my old 3rd Year Optics textbook, and I cannot find the method for answering this problem. Try reposting this in the "Advanced" forum.
