Raman Effect : Raman scattering or the Raman effect ( /ˈrɑːmən/) is the inelastic scattering of a photon. It was discovered by Sir Chandrasekhara Venkata Raman and Kariamanickam Srinivasa Krishnan in liquids‚[1] and by Grigory Landsberg and Leonid Mandelstam in crystals.[2][3] When light is scattered from an atom or molecule‚ most photons are elastically scattered (Rayleigh scattering)‚ such that the scattered photons have the same energy (frequency) and wavelength as the incident photons.

Zeigarnik Effect The Zeigarnik Effect is named after the Russian psychologist‚ Bluma Zeigarnik (1926)‚ who noticed an odd thing while sitting in a restaurant in Vienna. The waiters seemed only to remember orders which were in the process of being served‚ but little recollection of the completed orders. Zeigarnik went back to her lab to test out a theory about what was going on with the waiter. More than fifty years after the Bluma Zeigarnik study‚ Kenneth McGraw and his team returned to

Stroop effect and reading process Abstract This study evaluated the effect of congruency of color ink and color name on reading process. The 30 participants of the experiment were assigned to sets 1(a condition wherein congruent color names and ink color were presented first before the incongruent set of words‚ and 2 (reverse of set 1) by random selection. Participants were called in the laboratory two at a time‚ one of them from set 1 participants and the other from set

The Tyndall effect‚ also known as Tyndall scattering‚ is light scattering by particles in a colloid or particles in a fine suspension. It is named after the 19th-century physicist John Tyndall. It is similar to Rayleigh scattering‚ in that the intensity of the scattered light depends on the fourth power of the frequency‚ so blue light is scattered much more strongly than red light. An example in everyday life is the blue colour sometimes seen in the smoke emitted by motorcycles‚ in particular two-stroke machines
