Double slit experiment wavelength of light used

Click For Summary
SUMMARY

The discussion centers on calculating the wavelength of light used in the double slit experiment, specifically using the formula λ = (0.4mm * 1.1mm) / 800mm, which results in a wavelength of 0.00055mm. The participants emphasize the importance of verifying calculations independently rather than relying solely on forum feedback. Additionally, they highlight the necessity of reviewing past notes to reinforce understanding of the concepts involved.

PREREQUISITES
  • Understanding of the double slit experiment
  • Familiarity with wavelength calculations
  • Basic knowledge of light properties
  • Ability to manipulate and convert units (e.g., mm to m)
NEXT STEPS
  • Research the principles of wave-particle duality in quantum mechanics
  • Explore the mathematical derivation of the double slit experiment formula
  • Learn about the significance of wavelength in interference patterns
  • Investigate the impact of different light sources on experimental outcomes
USEFUL FOR

Students studying physics, educators teaching quantum mechanics, and anyone interested in the principles of light and wave behavior in experiments.

Homework Statement
Slit spacing is 0.4mm(a); fridge separation is 1.1mm(b); slit-screen distance is 0.8m(D).
Wavelength of light used is?
Relevant Equations
λ = (a*b)/D
0.8m -> 800mm
λ = (0.4mm*1.1mm)/800mm
= 0,00055mm
is it right?

I am past that 3 months ago, forgot how to solve.
