Why microwaves are used in radar not radiowaves?

Explanation

To understand why microwaves are used in radar instead of radio waves, we can analyze the properties of both types of electromagnetic waves. Here’s a step-by-step explanation:

### Step 1: Understanding Wavelength and Frequency
- **Definition**: Electromagnetic waves, including microwaves and radio waves, have different wavelengths and frequencies. The wavelength (λ) is the distance between successive peaks of the wave, while frequency (ν) is the number of wave cycles that pass a point in one second.
- **Relationship**: The speed of light (c) is constant, and it relates wavelength and frequency through the equation:
\[ c = λν \]
