When the separation between the central maxima of the two objects is greater than a separation between central maximum of a first object and the first minima of the first object, then objects are said to be
The diameter of an objective of a telescope, which can just resolve two stars situated at an angular displacement of ${10^{ - 4}}$ degree, should be $\left( {\lambda = 5000\,{A^0}} \right)$
A beam of natural light falls on a system of 5 polaroids, which are arranged in succession such that the pass axis of each Polaroid is turned through $60^0$ with respect to the preceding one. The fraction of the incident light intensity that passes through the system is

In double refraction, the stationary image can be produced by :
Consider the following statements A and B. Identify the correct statements.
(A) Polarized light can be used to study the helical structure of nucleic acids.
(B) Optical axis is a direction and not any particular line in the crystal.
