use the wave equation to calculate the speed with a frequency of 1 million herts and wavelenghth of 300
+33616 Speed = frequency*wavelength
You haven't given the units of length!
If we assume wavelength = 300 m then, with frequency = 106 s-1
$${\mathtt{speed}} = {{\mathtt{10}}}^{{\mathtt{6}}}{\mathtt{\,\times\,}}{\mathtt{300}} \Rightarrow {\mathtt{speed}} = {\mathtt{300\,000\,000}}$$ m/s
