The main drawback of huygen's theory was
Failure in explanation of rectilinear propagation of light
A failure of experimental verification of ether medium
failure to explain the formation of newton's rings
Both $(a)$ and $(b)$
Newton postulated his corpuscular theory on the basis of
Wavefront of a wave has direction with wave motion
In the adjacent diagram,$ CP$ represents a wavefront and $AO$ & $BP$, the corresponding two rays. Find the condition on $\theta$ for constructive interference at $P$ between the ray $BP$ and reflected ray $OP$
According to corpuscular theory of light, the different colours of light are due to
Spherical wavefronts shown in figure, strike a plane mirror. Reflected wavefront will be as shown in
