        The diameter of objective of a telescope is 1m. Its resolving limit for the light of wavelength \[4538\overset{\text{o}}{\mathop{\text{A}}}\,\], will be :

    A)  \[2B_{0}^{{}}\]

    B)  \[\sqrt{2}B_{0}^{{}}\]

    C) \[B_{0}^{{}}\]   

    D)  none of these

    Correct Answer: A

    Solution :

                    Here : \[\text{CuS}{{\text{O}}_{\text{4}}}\text{+NaOH(aq)}\] \[\text{CuS}{{\text{O}}_{\text{4}}}+\text{N}{{\text{a}}_{\text{2}}}\text{C}{{\text{O}}_{\text{3}}}\] Resolving limit \[CH\equiv CH+HBr\to X\]                                 \[\text{MgC}{{l}_{\text{2}}}.\text{CaSi}{{\text{O}}_{\text{3}}}.\text{2}{{\text{H}}_{\text{2}}}\text{O}\] \[\text{CaSi}{{\text{O}}_{\text{3}}}.\text{MgC}{{\text{O}}_{\text{3}}}\]
