Question
**Topic: Critical Frequency for Reflection at Vertical Incidence** The question explores the concept of critical frequency in the context of radio wave propagation. It asks: "What is the critical frequency for reflection at vertical incidence if the maximum value of electron density is \(1.24 \times 10^6 \, \text{cm}^{-3}\)?" This involves calculating the critical frequency, which is the highest frequency that can be reflected back to Earth by the ionosphere. The critical frequency is determined by the electron density of the ionosphere.
