$ The Price is Ligh
The Price is Light! Light is the only thing we SEE.
Some Ancient Greeks believed that light traveled from our eyes to the OBJECTS we look at. Arabian scientist, Alhazen (965 -1039) theorized light traveled from the OBJECTS to our eyes.
Abu Ali Hasan Ibn al-Haitham
Also, scientists from the Greeks to Sir Isaac Newton have considered light to be a stream of PARTICLES due to the fact
LIGHT TRAVELS IN STRAIGHT LINES
Empedocles from Greece and a Dutch physicist, Charles Huygens--
--a contemporary of Newton, argued light could be explained as behaving like a WAVE.
Thomas Young supported Huygens’ theory by demonstrating when light passes through a narrow opening, it can spread out and DIFFRACT with light passing through another opening.

Diffraction is the bending of a WAVE around a barrier, such as an obstacle or the edges of an opening.
The amount of diffraction depends on the size of the WAVELENGTH compared with the size of the slit or obstruction.
In 1905, Albert Einstein described light as consisting of massless bundles of concentrated energy called PHOTONS.
? Which scientists believed light behaved as particles?
Newton Einstein
? Which scientists believed light behaved as a wave?
Empedocles Huygens
Scientists now agree light has a dual nature, part PARTICLE and part WAVE.
