[QUOTE="TimeFlipper, post: 200020, member: 6456"] Yes Cobber you are perfectly correct..In a vacuum Light travels at 300milion meters per second...And when Light travels in our atmosphere, it drops down to 299million, 792thousand, 458 meters per second...However, to keep calculations simpler, especially for Radio Hams and figuring out our antenna lengths, we will always use the 300milion meters per second calculation.... For example, if we want to know the length in meters, for making a resonant half wave dipole on 30Mhz, we divide 30mhz into 300 (300/30=10 meters in length)...Essentially what we are doing is simply converting Megahertz into Meters...And if we want to convert Meters back into Megahertz, we divide 10meters into 300 (300/10=30Mhz frequency) For simplicity, we knock off the 6 noughts in 300, 000, 000 Meters, and the 6 noughts in 30, 000, 000Cps (Cycles Per Second)...We are therefore left with 300/30..:)..
