'. The persistence of vision is approximately one eight of a second. Even though human eye has the property of accommodation, the muscles cannot be strained beyond a limit and hence if the object is very close to the eye, clear image is not formed on the retina. Thus, ..

In man, the eyes are frontal and thus the vision is binocular. This means that the image finally perceived is the result of the information received from both the eyes. Binocular vision results in stereoscopic vision that gives a 3-dimensional image. Thus, this capability of st..

The mucuous membrane lining the digestive, respiratory and urinogenitaltracts secrete mucus which traps the micro organisms and immobilises them. This is then eliminated with the sputum or removed with the faeces Secretions of tears and movements of eyelids flush out the microorganisms se..

Polygraph is a simple instrument that records qualitative changes in physiological parameters. These parameters include vital changes like cardiac variables (ECG), heart pulse rate (HR), relative blood pressure (BP), rate of breathing and so on. Popularly called the lie detector. A modern imp..

It should be borne in mind that the uncertainty is not due to lack of sufficiently refined techniques but it is due to the fact that one cannot observe microscopic things without disturbing them. No instrument can observe the position of an electron without affecting its motion. In other word..

It is an instrument in which plane mirrors are used to fold light so that the image of an object can be brought down to a lower level. It is used for observing enemy movements from trenches without any danger of being seen. Sailors on submarines use periscopes to see things above the wate..
