Another Q about double-slit experiment

In summary, the Young's double-slit experiment was performed with 589nm light and a distance of 2.00m between the slits and the screen. The tenth interference minimum was observed 7.26mm from the central maximum. Using the formula for distance from the central maximum, the spacing on the slits was determined to be 1622589m. The formula for determining intensity was not applicable in this case.

Homework Equations


Iavg = (Imax) cos^2 [(pi d sin angle) / lambda]
(it is very frustrating not being able to insert relevant symbols :grumpy: )

hm you seem to be using the wrong formula, in this case we are not measuring the intensity but using: distance from central max= (wavelength * distance to screen*order number)/spacing of slits. Hoped that helped

589nm x 2.00m x 10 / .00726m = spacing of slits

1622589m between slits?

Sorry to change the topic, but look here for some info on LaTeX https://www.physicsforums.com/showthread.php?t=8997 if you want to make the equations look right
 

What is the double-slit experiment?

The double-slit experiment is a famous physics experiment that demonstrates the wave-particle duality of light and matter. It involves shining a beam of particles or light through two parallel slits and observing the resulting interference pattern on a detector screen.

Why is the double-slit experiment important?

The double-slit experiment is important because it challenges our understanding of the fundamental nature of particles and light. It also has practical applications in fields such as quantum mechanics and optics.

What is the significance of the interference pattern in the double-slit experiment?

The interference pattern in the double-slit experiment shows that particles or light waves can behave as both particles and waves simultaneously. This supports the wave-particle duality theory and has significant implications for our understanding of the nature of matter and energy.

How does the double-slit experiment relate to quantum mechanics?

The double-slit experiment is a key example used to explain the principles of quantum mechanics, such as superposition and wave-particle duality. It also has important applications in the development of quantum technologies.

Are there any variations of the double-slit experiment?

Yes, there are variations of the double-slit experiment that have been conducted with different types of particles, such as electrons and atoms, and with different setups, such as using a single slit or multiple slits. These variations have helped to further our understanding of the nature of particles and light.
