Research and write about the psychologist Leon Festinger and his theory of cognitive dissonanceExplain the theory with an example. Mention an experience when youconsciously or unconsciously, modified your behavior or to reduce the feelings of dissonance (for example, justifying something you did or bought, which you may have had second thoughts about). Alsoresearch and write about Festinger's social comparison theory, and discuss upward and downward social comparison Provide examples from your own life where you engaged in this comparison process to assess yourself in comparison to others. Please answer quickly!!!

In 1964, Festinger moved from social psychology to research on visual perception. ... His social psychological research concerned how people resolve conflict (group dynamics), ambiguity (social comparison), and inconsistency (cognitive dissonance)—all manifestations of pressures for uniformity. Festinger's theory proposes that inconsistency among beliefs or behaviours causes an uncomfortable psychological tension (i.e., cognitive dissonance), leading people to change one of the inconsistent elements to reduce the dissonance or to add consonant elements to restore consonance.

Leon Festinger was one of the most important figures in modern psychology and contributed several theories that are still important today for our understanding of the communication process, particularly the individual's exposure to communication and processes of opinion formation and judgment

Explanation:

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.
