3Khz 100Km
VLF Myriametric
30Khz 10Km
LF Kilometric
300Khz 1Km
MF Hectometric
3Mhz 100m
HF Decametric
30Mhz 10m
VHF Metric
300Mhz 1m
UHF Decimetric
3Ghz 10cm
SHF Centimetric
30Ghz 1cm
EHF Millimetric
300Ghz 1mm

Its easyer to right it length ways across the page.

First thing to do in the exam is remeber

Very Lovely Madens Have Very Usefull Sex Equipment. (First letter of each Freq Band)

Start on top 3 30 300, 3 30 300 inbetween each letter. check start with a 3 end with a 300, then put in the Khz, Mhz & Ghz as apllicable

Below this start at the Right with 1 millimeter, then times by ten
10mm = 1cm
10 x 1cm = 10cm
10 x 10cm = 1m
ect ect

Check theres 2 1's at the start, and ends on 100 without any dody maths inbetween

you can just about figure out the wavelenght bands Right to left again.

Milimetric after the milimetrs
10 * 1mm = Centemeter - Centimetric
10 * 1cm = Deciameter - Decimal like the decimal point (fractions of a tenth ect)
10 * 10 = 100cm - meter - Metric
10 meters - DecaMeter Deca - oposite of Deci, oposite side of the Metric
then its just H, K, M.

It's a pretty easy table to replicate in the exam with practice, & in both RNav & A/C Gen its a good 2 questions quickly in the Bank.

Good luck with the Exams
