Detailed explanation-1: -Binding Light This new form of light carries properties of both particles. Normally, light would interact with a huge number of electrons.

Detailed explanation-2: -Strange new property of light discovered-first in 27 years. Using two time-delayed laser pulses shot into argon gas, optical physicists have discovered a whole new property of light called self-torque. Shining this type of laser on a flat surface yields a croissant-shaped puddle of light.

Detailed explanation-3: -The credit of the discovery of the law of refraction is given to Willebrord Snellius (1580–1626) who derived it using trigonometric methods in 1621.

Detailed explanation-4: -Born around a thousand years ago in present day Iraq, Al-Hasan Ibn al-Haytham (known in the West by the Latinised form of his first name, initially “Alhacen” and later “Alhazen”) was a pioneering scientific thinker who made important contributions to the understanding of vision, optics and light.
