Question

The maximum frequency of transmitted radio waves above which the radio waves are no longer reflected back by ionosphere is ______.

(N = maximum electron density of lonosphere, g = acceleration due to gravity)

Options

• gN

• gN²

• g`sqrt"N"`

• g²N²

Answer 1

The maximum frequency of transmitted radio waves above which the radio waves are no longer reflected back by ionosphere is `underlinebb("g"sqrt"N")`.

(N = maximum electron density of lonosphere, g = acceleration due to gravity)

Explanation:

The maximum frequency of radio waves that are reflected back by the ionospheric layer after being sent there is given by the formula g`sqrt"N"`.
