Diffraction of Light (Single Slit)

Click For Summary
SUMMARY

The discussion centers on the diffraction of light through a single slit, specifically addressing the identification of dark and bright fringes in the diffraction pattern. The initial guess regarding the third dark fringe being the second order dark fringe and the second bright fringe as the first order bright fringe is challenged. Participants emphasize the importance of drawing a diffraction pattern and utilizing provided information for accurate calculations.

PREREQUISITES
  • Understanding of wave optics principles
  • Familiarity with diffraction patterns
  • Knowledge of fringe order in single slit diffraction
  • Ability to perform calculations involving wavelength and slit width
NEXT STEPS

Homework Statement
What is the order for second bright fringe?
Relevant Equations
The second bright fringe from a 633𝑛𝑚 light source overlaps with the third dark fringe from an unknown light source. Calculate the wavelength of the unknown light source.
My initial guess... Third dark fringe is 2nd order dark fringe and second bright fringe is 1st order bright fringe. Is this the correct guess?

HI,

You are not supposed to guess ! Draw a diffraction pattern (or find one) and use the given info to calculate.
