Sin—In reply to Fax, 1 think thee the following information may be of help. The speed of radio waves is approximately 300,000,000 metres. per second. A wave has length (metres) from crest to crest, and frequency (number of crests per second). A wave of length 600 metres, and. froquency $00,000 eyotes (500 kllocycles) per second will travel 300,-/ 000,000 metres in one second, From this it will be seen that:—Metres x ailoeyeles=800,000. Simple division of 300,000 by metres will give kilocycles, and vice versa, Tt should be noted' that the broadcast band of some receivers calibrated In K. C. has a nought omitted. A magaeycle 1,000 K, C, Thus:—20,000 K, C= 20 M, C.=18\ metres, For convenience in short wave work, a magazine hag "Short Wave Gratt" prints current tists of short-wave stations and their frequency and wave length. Such magazine can be obtained in Bubbling Well Road near Gordon Road and probably elsewhere.
