A Simple Algorithm to Calculate Wavelength from Frequency

INPUT: frequency, band, units

OUTPUT: wavelength

CONSTANTS:

• METERS TO FEET = 3.28
• SPEED OF LIGHT = 299,792,458 meters per second

IF band = "AM"

	THEN
    		wavelength = SPEED OF LIGHT/frequency

IF band = "FM"

	THEN
    		wavelength = SPEED OF LIGHT x 1000/frequency

IF units = "feet" [Note: units are, by default, in meters]

	THEN
    		wavelength = wavelength x METERS TO FEET

OUTPUT: wavelength

This computer program needs to be translated to a real computer language. You'll have to decide what language you want to use - and then you'll have to translate it into that language. However, that shouldn't be hard. If you can't do it yourself, see if you can find a teacher, a friend or an older student to help you.

The program that calculates the value of wavelength you saw on your screen was written in Perl, which is a language that people use when they are writing Web Sites. It is a little more complicated than this program because it has to "parse" (or understand) some of the ways the web pages "talk" to the computers that compute the wavelength.
