Radiowaves diffract pronouncedly around buildings, while light waves, which are electromagnetic waves, do not, why? 

Explanation

### Step-by-Step Solution

1. **Understanding Diffraction**:
- Diffraction is the bending of waves around obstacles and openings. It occurs when the size of the obstacle is comparable to the wavelength of the wave.

2. **Comparing Wavelengths**:
- Radio waves have much longer wavelengths, typically in the range of meters (e.g., a few meters to kilometers).
- Light waves, on the other hand, have much shorter wavelengths, approximately \(10^{-9}\) meters (nanometers).
