Question
The wave-like character was experimentally proved for light by:

Answer

  1. Young
Explanation:
Newton's particle theory remained accepted for a long time when it was challenged by the double-slit experiment of Thomas Young (1773-1829) in 1801. This experiment clearly established that light coming from two coherent sources interferes and produces maxima and minima depending on the path difference.
