  • question_answer
    The frequency of \[\gamma -rays,\] X-rays and ultraviolet rays are a, b and c respectively. Then:

    A)  \[a>b>c\]        

    B)       \[a<b<c\]

    C)  \[a=b=c\]

    D)       \[a>c>b\]

    Correct Answer: A

    Solution :

    Frequency of radiations given are listed below:
    Waves Frequency (in Hz)
    1. \[y-\]rays \[3\times {{10}^{21}}\] to \[3\times {{10}^{18}}\]
    2. \[X-\]rays \[3\times {{10}^{18}}\]to \[3\times {{10}^{16}}\]
    3. Ultraviolet radiation \[3\times {{10}^{16}}\]to \[7.5\times {{10}^{14}}\]
    Thus, correct order is
    \[a>b>c\]
