The goal of using a double slit experiment set-up is to demonstrate the wave-particle duality of light and other particles. This experiment shows that particles, such as photons or electrons, can exhibit both wave-like and particle-like behavior depending on how they are observed.
In the double slit experiment, a beam of particles is directed towards a barrier with two slits. When the particles pass through the slits and hit a screen on the other side, an interference pattern is observed, similar to what would be seen with waves. This interference pattern demonstrates the wave-like nature of the particles.
However, when detectors are placed at the slits to determine which slit the particles pass through, the interference pattern disappears and a particle-like pattern is observed. This shows that the act of observation can influence the behavior of the particles, demonstrating their particle-like nature.
Overall, the goal of the double slit experiment set-up is to provide evidence for the wave-particle duality of particles and to further our understanding of the fundamental nature of matter and energy.

Goal of Double Slit Experiment Setup:
The double slit experiment is a經典的光學實驗 that demonstrates the wave-particle duality of light. The goal of using this setup is to investigate the fundamental nature of light and matter.
Setup:
- A monochromatic light source (e.g., a laser)
- Two closely spaced slits (e.g., created using a razor blade or a grating)
- A screen placed behind the slits
Procedure:
1. Light from the source passes through the slits and interferes with itself on the screen.
2. According to classical wave theory, a single, bright fringe would be expected directly opposite the slits.
3. However, the experiment reveals a pattern of alternating bright and dark fringes (bands), indicating interference between the waves passing through the slits.
Key Observations:
- The width of the fringes depends on the wavelength of light and the distance between the slits.
- The intensity of the bright fringes is proportional to the square of the amplitude of the light wave.
- The dark fringes correspond to points where the waves cancel each other out.
Interpretation:
The double slit experiment has several key implications:
- Wave-Particle Duality: Light exhibits both wave-like and particle-like properties. As waves, light can interfere with itself. As particles (photons), light can be absorbed and emitted.
- Probability Distribution: The distribution of light intensity on the screen is a probability distribution. The intensity at each point represents the probability of detecting a photon there.
- Uncertainty Principle: The position and momentum of a photon cannot be precisely determined simultaneously. The double slit experiment illustrates this by showing that a single photon can pass through both slits at the same time.
Applications:
The double slit experiment has led to numerous technological applications, including:
- Interferometry (e.g., measuring distances and surface profiles)
- Lasers (based on constructive interference)
- Quantum computing (exploiting the particle-like behavior of light)
