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) |
|
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. |
