Diffraction is common in sound but not comon in light waves. Why ?

Explanation

### Step-by-Step Solution:

1. **Understanding Diffraction**:
- Diffraction is the bending of waves around obstacles and openings. It occurs when a wave encounters an obstacle or a slit that is comparable in size to its wavelength.

2. **Wavelength Comparison**:
- The wavelength of sound waves is approximately in the order of 1 meter, while the wavelength of light waves is in the order of \(10^{-6}\) meters (or micrometers).
