Wavelength and Frequency conversionEdit

λ = c/ν

• λ (lambda) is the wavelength
• c is the speed of light
• v is the frequency

ExampleEdit

6 meters is what frequency?

$\lambda=\frac{c}{v}$ or $\text{wavelength}=\frac{\text{speed of light}}{\text{frequency}}$
$\lambda*v=c$
$v=\frac{c}{\lambda}$
$v=\frac{3*10^8}{6}$
$v=\frac{300,000,000}{6}$
$v=50,000,000$
$50,000,000 Hz\text{ is }50 MHz$
v=50 MHz
6 meters is 50 MHz.

UnitsEdit

Note that c is meters/second, that λ is meters, and v (nominally expressed in megahertz, or millions of hertz) is simply "/second".

ShortcutEdit

• Wavelength in meters equals 300 divided by frequency in megahertz.
• Frequency in megahertz equals 300 divided by wavelength in meters.

This expresses the speed of light as 300x10^6, and since megahertz is "millions of hertz" and one million is 1x10^6, we can ignore the scientific notation. Given a 6 meter band, what's the frequency of the band?

$v=\frac{300}{6}$
$v=50$
v=50 MHz
6 meters is 50 MHz.
