Explain Brain or Detector - Mechanism of Colour Perception
The fibre identification of colour takes place in the brain. If any of these four pre-requisites are not present, the perception will not take place. In case of colour perception, the reaction time is very fast. The perception is the result of the interaction of light source, object, receiver and detector. The receiver is eye and the detector is brain. When light falls on an object, there is an imbalance of radiant energy and a number of phenomena may occur due to this imbalance, which include reflection, absorption and transmission. The colour perceived is dependent on the reflected light. Reflected ray is received by the retina of the eye, which gets stimulated, the impulse is transferred to the nerve fibres via optic nerve and finally, it goes to the brain. There are special centers in the brain where colour is identified. To conclude, colour is the stimulus that results from the detection of light, after it has interacted with an object. Three factors are involved: a light source, an object and a receiver-detector the light may be reflected, transmitted, absorbed or refracted by an illuminated object.

Why does a glacier move? It moves due to the huge pressure of the ice and snow lowers the freezing point of its lower layers, causing by to melt.
