...limited budget, he early decided that he could not compete with the elaborate offerings of direct mail advertisers. Instead, he makes his booklets chaste and subdued, thus getting his message heard, says he, much as a short-wave radio station competes with WJZ-i.e., by using a different wavelength...
...every Tuesday evening at 8 o'clock through the non-commercial shortware station WIXAL, of the World-Wide Broadcasting Foundation, Boston. Financed by private donations and the Rockefeller Foundation, WIXAL is devoted entirely to educational and cultural programs. The Harvard series are broadcast on a frequency of 6.04 megacycles, wavelength 49.6 meters, and are audible around the world...
...Lemmon rigged on the roof over the commissioner's hearing room a temporary aerial, demonstrated a typewriter on which the keys click in response to radio impulses, picked up a message typewritten through the air from a Georgetown laboratory. Engineer Lemmon told the commission that one television station wavelength assignment would be roomy enough for 1,125 radio-typewriter channels, asked that his company be assigned wavelength space as wide as one television station is for experiment with radio business machines...
...entire basic mechanism of television might be changed. 3) Either the effective range of television's video wave must be lengthened beyond the present so-mile radius or the band of wave lengths needed for a television station must be reduced radically to solve the problem of wavelength congestion...
...frequency of energy oscillations determines the wave length of the emitted light, just as the oscillation frequency of a radio transmitter determines the length of the radio waves. When his particles were speeded up to velocities around 1,000 miles per second, Dr. Ives observed a change in wavelength which indicated that the fast-moving atomic clocks were running slow, as the theory predicts they should...
