The correct Answer is:
To solve the question regarding the frequency range of radio waves from 300 MHz to 3000 MHz, we will follow these steps: ### Step 1: Identify the given frequency range The frequency range provided in the question is from 300 MHz to 3000 MHz. ### Step 2: Understand the frequency bands We need to recall the different frequency bands and their corresponding ranges: - **High Frequency (HF) Band**: 3 MHz to 30 MHz - **Very High Frequency (VHF) Band**: 30 MHz to 300 MHz - **Ultra High Frequency (UHF) Band**: 300 MHz to 3000 MHz (or 3 GHz) - **Super High Frequency (SHF) Band**: 3 GHz to 30 GHz ### Step 3: Compare the given range with the frequency bands Now, we will compare the given frequency range (300 MHz to 3000 MHz) with the defined frequency bands: - The lower limit of the given range (300 MHz) matches the lower limit of the UHF band. - The upper limit of the given range (3000 MHz) matches the upper limit of the UHF band. ### Step 4: Conclusion Since the entire frequency range of 300 MHz to 3000 MHz falls within the UHF band, we can conclude that the radio waves of frequency 300 MHz to 3000 MHz belong to the **Ultra High Frequency (UHF) Band**. ### Final Answer: The radio waves of frequency 300 MHz to 3000 MHz belong to the **Ultra High Frequency (UHF) Band**. ---
