Answer to Question #155440 in Quantum Mechanics for Satyam

Question

Calculate the critical frequency for the E layer if maximum ionic densities are 3 x 10⁶

A.15.58 x 10⁶

B.15.58 kHz

C.1.58 x 10³

D.None of the above

Answer 1

The critical frequency for the E layer can be calculated as follows:

$$f_c=9\sqrt{N_{max}},$$

$f_c=9\cdot\sqrt{3\cdot10^6\ \dfrac{electrons}{m^3}}=15.58\cdot10^3\ Hz =15.58\ kHz.$

Answer:

$f_c=15.58\ kHz.$
