This is in contradiction to the
prediction made by using the corpuscular model of light It was much
later confirmed by experiments where it was shown that the speed of
light in water is less than the speed in air confirming the prediction of the
wave model; Foucault carried out this experiment in 1850 The wave theory was not readily accepted primarily because of
Newton’s authority and also because light could travel through vacuum

and it was felt that a wave would always require a medium to propagate
from one point to the other However, when Thomas Young performed
his famous interference experiment in 1801, it was firmly established
that light is indeed a wave phenomenon
