    Maximum usable frequency (MUF) in F-region layer is x, when the critical frequency is \[60\text{ }MHz\]and the angle of incidence is \[70{}^\circ \]. Then calculate x.

    A) \[122\,MHz\]

    B) \[216\,Hz\]

    C) \[175\,MHz\]

    D) \[75\text{ }Hz\]

    Correct Answer: C

    Solution :

    [c] \[MUF=\frac{{{f}_{c}}}{\cos \theta }=\frac{60}{\cos \,70{}^\circ }=175\,MHz\]
