A group of scientists from Harvard University who will observe the celestial event from Ak-Bulak, in Russian Turkestan, are cooperating with the RCA laboratories to determine how the action of the shadow on the earth's outer atmosphere, atmo-sphere, known as the ionosphere, will affect radio transmission. The Harvard scientists will send out radio waves to measure changes taking place in the "radio ceiling" of the world in the path of totality, and the RCA laboratory at Riverhead, L. I., will observe possible changes in radio signals crossing the path of the eclipse, from points in Australia, the Philippines and Japan to the United States. i Knowledge gained from the tests is expected to enable more accurate selection of radio wavelengths for transmission over long distances through various degrees of daylight and darkness. |
