Discovered that the upper layer of the ionosphere, called the F-region or
Appleton layer, reflects radio waves. The discovery established the possibility of
radio communication over long distances, and was also fundamental to the
development ...
Comparison of the wave-lengths which each of these two mirrors will just reflect
shows that the Appleton layer is just about four times as strong a reflector. Waves
which are too short for the Heaviside layer can go on travelling upwards and ...

Other scientists and the public named this "F-Region" after its discoverer, as "
Appleton Layer". This dicovery opened up roads to vast areas of research and
also its utility in the technological developments. R. A. Watson- Watt called this

It was in the course of the study of these phenomena that Appleton found in 1927
that there must exist still another reflecting layer beyond the one mentioned
previously, at a height of about 230 km. This so-called Appleton layer is still more
