The maximum
frequency for reflection of sky waves from a certain layer of the ionosphere is
found to be where is the,
maximum electron density at that layer of the ionosphere. On a certain day it
is observed that signals of frequencies higher than 5 MHz are not received by
reflection from the F1 layer of the ionosphere while signals of
frequencies higher than 8 MHz are not received by reflection from the F2
layer of the ionosphere. Estimate the maximum electron densities of the F1
and F2 layers on that day.
