    Answer:

    1. Light is electromagnetic waves while sound is mechanical.

    Light wave is transverse and sound is longitudinal.

    Explanation:

    2.

    <i = <r

    3.

    when distance between source and obstacle and distance between obstacle and screen is finite then the diffraction is fresnal diffraction

    when distance between source and obstacle and distance between obstacle and screen is infinite then the diffraction is Fraunhofer’s diffraction
