Hi..,
Case1:-
Excluding this reason: Persistence of vision.
Why do *Far* objects appear as "Small" to our eye?
Case2:-
How to determine the "Wavelength & Frequency" of the visible spectrum or most probably for the "Given" light without using the *speed of light* concept?
Case3:-
Hypothetical case: For 10min for the sake of discussion we will think that Light is *particle* in nature
then, how can we explain the concept of *colors* of the light?
Ibn al-Haytham(Alhazen) in his "Book of optics" voted for particle nature, then, why didn't he get any confusion while explaining the colors concept?
so as Newton..too..,
Case4:-
We didn't know what exactly is Light? or atleast what is a Photon?
then,
what's the principle behind the image sensor(CCD) in a camera? On what principle does it work?
(a) particle or (b) wave nature.
