Give the frequency ranges of the following (i) High frequency band (HF) (ii) Very high frequency band (VHF) (iii) Ultra high band (UHF) (iv) Super high frequency band (SHF).

Explanation

To provide a step-by-step solution to the question regarding the frequency ranges of different bands, let's break it down as follows:

### Step 1: Identify the High Frequency Band (HF)
- The High Frequency (HF) band is defined in the radio frequency spectrum.
- **Frequency Range**: 3 MHz to 30 MHz.

### Step 2: Identify the Very High Frequency Band (VHF)
- The Very High Frequency (VHF) band follows the HF band in the radio frequency spectrum.
