What band is best suited for communicating via meteor scatter?
33 centimeters
6 meters✓پاسخ درست
2 meters
70 centimeters
توضیح
Meteor trails ionise the atmosphere for only a fraction of a second to a few seconds, and the lower the frequency the longer and stronger the reflection. Of the choices offered, 6 metres is the lowest frequency and gives the most usable meteor-scatter reflections.
