    The frequency of X-rays;\[\gamma \text{-}\]rays and ultraviolet rays are respectively a, b and c then.   JEE Main Online Paper (Held On 26-May-2012)  

    A) \[a<b;b>c\]                       

    B)                        \[a>b;b>c\]

    D)                        \[a=b=c\]

    Correct Answer: A

    Solution :

                    Frequency range of \[\gamma -ray,\] \[b={{10}^{18}}-{{10}^{23}}Hz\] Frequency range of X-ray, \[a={{10}^{16}}-{{10}^{20}}Hz\] Frequency range of ultraviolet ray, \[c={{10}^{15}}-{{10}^{17}}Hz\] \[\therefore \]\[a<b;b>c\]
