Frequency = 1 / (period) = 1/.4 = 2.5 Hz

Oh, what a lovely question! To find the frequency of a wave when you know the period, you simply take the reciprocal of the period. So, if the period is 40 seconds, the frequency would be 1 divided by 40, which equals 0.025 Hz. Isn't that just a happy little calculation?
It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.
t = 0.025 s Then f = 1/t f = 1/0.025s f = 40^(-s) or 40 Hz.
