    How would you explain the double slit experiment in the simplest way possible but not missing out any physics.
    I'm just going to give you a few key bullet points here, but if you have any more questions then feel free to ask!

    • What is the point?!: The double-slit experiment is important for two reasons; it can be used to find wavelength, and it proves that light interferes (thus providing evidence for the wave nature of light).
    • What it involves: Light passes through a single slit first (to make it coherent, otherwise you would just end up with a lot of interference), and then a double slit. This makes the light diffract through the double slits, which then interfere with each other to produce light/dark fringes.
    • Calculating wavelength: The formula is w = λD/s, where w is the fringe spacing, λ is the wavelength, D is the slit-screen distance, and s is the slit separation. All of these are measured in metres.

    I think that's about it, hope this helps!
