An eletromagnetic wave of frequency 28 MHz passes through the lower atmosphere of earth and gets incident on the ionosphere.Shall the ionosphere reflects these waves?

Explanation

To determine whether the ionosphere will reflect an electromagnetic wave of frequency 28 MHz, we can follow these steps:

### Step 1: Understand the Frequency Range of the Ionosphere
The ionosphere has the ability to reflect electromagnetic waves, but this ability depends on the frequency of the waves. Generally, the ionosphere reflects radio waves with frequencies below a certain threshold.

**Hint:** Research the frequency range that the ionosphere can reflect.

### Step 2: Identify the Given Frequency
