    Hey guys so ive been revising and making notes for AS physics (AQA New Spec) and I was reading the specification I got pretty confused with Interference & diffraction and was wondering if anyone help explain it to me

    The main stuff (from the spec) that I need to know

    - Interference and diffraction using a laser as a source of monochromatic light.

    - Young’s double-slit experiment: the use of two coherent sources or the use of a single source with double slits toproduce an interference pattern.

    - Production of interference pattern using white light.

    - Appearance of the diffraction pattern from a single slit using monochromatic and white light.

    Source:
    Spoiler:

    The main confusion is what is the difference between interference and diffraction? The last two bullet points seem almost identical

    Thanks
