The full wave length of 10 MHz is 30 metres.
300 MHz: λ = about 3.278 feet.
The frequency can't be 30 Mhz 30 Mhz is a ham radio frequency but to calculate the wavelength, devide 300 by the frequency in Mhz that will give you 10 meters (300/ƒ)
750 million
An aerial length of 750 metres is required
10 to the power 7 Hz is 10 MHz, so that is HF (high frequency); this range of radio waves goes from 3 to 30 MHz.

Assuming you are asking what has a shorter wavelength 1 Mhz or 1 Ghz, then the answer is 1 Ghz. But the way the question was phrased, Mhz or Ghz, well 1000 Mhz is = 1 GHz. Note that 1 hz is just 1 cycle/sec. 1 Mhz is 1,000,000 cycles/sec and 1 Ghz is 1,000,000,000 cycles/sec. So to fit 1000 cycles in one second (as compared to 1 cycle in a second) the cycles have to be shorter (faster up and down sinusoidal wave).
The period of 1 MHz is 1 microsecond. The waveform is irrelevant.
Wavelength is calculated in MHz not Hz, and the formula is Wavelength = 300 / MHz
