What is meant by diffraction of light?

Explanation

**Step-by-Step Solution:**

1. **Definition of Diffraction**:
- Diffraction of light refers to the phenomenon where light waves bend around obstacles or spread out as they pass through narrow openings. This bending occurs when light encounters an edge or a slit that is comparable in size to its wavelength.

2. **Explanation of the Process**:
- When light waves travel and reach a sharp edge or a small aperture, they do not simply travel in straight lines. Instead, they bend around the edges and spread out into the region that would typically be in shadow if light were traveling in straight lines.
