British winner of the Nobel Prize for Physics in 1947 for his discovery of the so-known as Appleton layer of theionosphere, which is a dependable reflector of radio waves and as such is useful in communication. Different ionospheric layers reflect radio waves sporadically, relying upon temperature and time of day.He attained world reputation with his analysis into the propagation of electromagnetic waves and the characteristics of the ionosphere.

He confirmed that radio waves of wavelength sufficiently short to penetrate the lower area of the ionosphere are reflected through an higher region . This discovery made possible more reliable long-range radio communication and aided in the development of radar.
