Optical Illusions
An optical illusion is characterized by visually perceived images that differ from objective reality, arising due to physiological mechanisms of the human visual system or cognitive misinterpretations of sensory inputs.
Importance in UPSCUPSC में महत्व
Tested frequently in UPSC Prelims under Science and Technology (Physics/Biology overlapping concepts like total internal reflection, refraction, and human eye anatomy) and in Mains GS-3 for applications of science in daily life and cognitive phenomena.
