1. Security inks exploit the same principle that causes the vivid and constantly changing colours of a film of oil on water.

A. When two rays of light meet each other after being reflected from these different surfaces, they have each travelled slightly different distances.

B. The key is that the light is bouncing off two surfaces, that of the oil and that of the water layer below it.

C. The distance the two rays travel determines which wavelengths, and hence colours, interfere constructively and look bright.

D. Because light is, an electromagnetic wave, the peaks and troughs of each ray then interfere either constructively, to appear bright, or destructively, to appear dim.

6. Since the distance the rays travel changes with the angle as you look at the surface, different colours look bright from different viewing angles.

A notable weakness of the Indian bureaucracy is its failure to familiarize itself with modern management techniques, acquire new skills and tone up in professional efficiency. An equally unwelcome feature of the higher civil service is the lack of cost-consciousness. Rare, indeed, is the senior officer who is aware of the crucial significance of the compound rates of interest and realizes that money today and money two years hence are very different things.  The typical bureaucrat's lack of cost consciousness is partly responsible for his well-known tendency to avoid decision making.  A large number of top civil servants rue the day they are obliged to take a decision.  When it becomes no longer possible to postpone a decision, ______________________

Hello all, I wanted to know about the admission criteria for JBIMS, like which exam scores do they consider, does work experience and board examination scores matter?

I have a Maharashtra domicile, and I am in the final year of my graduation. (Bcom, MU) I intend to give CMAT in Feb 2015, so is that a wise decision considering I will be starting my prep from scratch? Can a person go about it, without joining a coaching institute? 

Any help will be appreciated. (:

Thank you. (oyejeetesh@gmail.com)
