Abstract
FOR some time experiments have been in progress in Cambridge to study the characteristics of long radio waves corresponding to frequencies of about 100 kc./s., reflected from the ionosphere at steep incidence, using senders about 100 km. from Cambridge; and recently there has been the opportunity of comparing the behaviour of these waves with that of very similar waves reflected obliquely from the ionosphere using senders about 900 km. distant. This comparison has revealed a number of interesting features, and in particular it has shown up a marked difference in behaviour during the occurrence of a ‘sudden ionospheric disturbance’. It is the purpose of this note to describe this difference and to compare the behaviour with that of waves of other frequencies.
