A
3.5 MHz to 4.0 MHz
B
4.5 MHz to 5.0 MHz
C
3.0 MHz to 3.5 MHz
D
4.0 MHz to 4.5 MHz
Answer Notes
The 80-metre band in Canada spans from 3.5 MHz to 4.0 MHz. A reliable way to estimate the frequency given the wavelength (or vice versa) is using the formula: Wavelength (in metres) ≈ 300 / Frequency (in MHz).
If you divide 300 by 80 metres, the result is 3.75 MHz, which falls right in the middle of the 3.5 to 4.0 MHz range. This makes it easy to remember the correct option.
The other options provided, such as 4.0 to 4.5 MHz, fall entirely outside this calculated estimation and represent frequencies allocated to other radio services, such as aviation or maritime communications.
