The correct Answer is:
To determine the main advantage of microwaves from the given options, let's analyze each option step by step: ### Step 1: Understand the properties of microwaves Microwaves are a type of electromagnetic wave with specific characteristics. They have longer wavelengths and lower frequencies compared to other electromagnetic waves. ### Step 2: Analyze the options 1. **Highly directive**: This means that microwaves can be focused into a narrow beam, allowing for precise targeting and communication. 2. **Moves at the speed of light**: While this is true for all electromagnetic waves, it is not a unique advantage of microwaves. 3. **Greater gain ratio**: This refers to the ability to amplify signals, but it is not the primary advantage of microwaves. 4. **High penetration power**: Microwaves can penetrate certain materials, but this is not their main advantage compared to their directive capability. ### Step 3: Identify the main advantage Among the options provided, the most significant advantage of microwaves is that they are **highly directive**. This property allows for the design of high-gain antennas, making them ideal for communication systems. ### Conclusion The main advantage of microwaves is that they are **highly directive**. ---
