Computing the Frequency of a Wavelength

Frequency = (C / Wavelength)

Where:

Frequency: Frequency of the wave in hertz (hz).
C: Speed of light.
Wavelength: Length of the wave.

NOTE: Both the speed of light and the wavelength have to be in the same measurement units.

 Speed of Light (cee) for Reference 29,979,245,800 cm/sec (3 x 1010 approx)299,792,458 m/sec (300 x 106 approx)983,571,056 ft/sec (984 x 106 approx)327,857,019 yards/sec299,792.458 kilometers/sec186,282.397 miles/sec (186 x 103 approx)161,874.977 nautical miles/sec (186 x 103 approx)

 EXAMPLE: What is the frequency of a radar with a 3 centimeter wavelength? Because our wavelength is centimetric; we must insert the speed of light in centimeters/sec; thus: (3 x 1010 cm/sec divided by 3 cm) = 10,000,000,000 Hz = 10,000 MHz The frequency of a 3cm radar is approximately 10,000 MHz. More precise numbers can be found by using the exact speeds instead of approximations.

Computing the Wavelength of a Frequency

Wavelength = (C / Frequency)

Where:

Wavelength: Length of the wave.
C: Speed of light.
Frequency: Frequency of the wave in hertz (hz).

NOTE: Both the speed of light and the wavelength have to be in the same measurement units.

 EXAMPLE: What is the Wavelength of a 300 MHz radar in centimeters? First, we must convert from MHz to Hz: 300 MHz * 1,000,000 = 300,000,000 Hz Because our wavelength is centimetric; we must insert the speed of light in centimeters/sec; thus: (3 x 1010 cm/sec divided by 300,000,000 Hz) = 100 cm The wavelength of a 300 MHz radar is approximately 100 cm. More precise numbers can be found by using the exact speeds instead of approximations.
