  • question_answer
    Two point white dots are 1 mm apart on a black paper. They are viewed by eye of pupil diameter 3 mm. Approximately, what is the maximum distance at which these dots can be resolved by the eye? [Take wavelength of light = 550 mm]

    A)  5m                                        

    B)  1 m                       

    C)        6m                        

    D)        3m

    Correct Answer: A

    Solution :

    We know \[|\overrightarrow{S}|=\sqrt{S_{x}^{2}+S_{y}^{2}}=\sqrt{{{(\sqrt{2})}^{2}}+{{(5\sqrt{2})}^{2}}}\] \[=\sqrt{52}km\]   \[\tan \theta =\frac{y\text{-componet}}{x\text{-}componet}\] \[=\frac{5\sqrt{2}}{\sqrt{2}}\] \[\therefore \] \[\theta ={{\tan }^{-1}}(5)\]   \[Time\propto {{C}^{x}}{{G}^{y}}{{h}^{z}}\]
