Name the phenomenon which is responsible for bending of light around sharp corners of an obstacle. Under what conditions does this phenomenon take place ? Give one application of this phenomenon in everyday life.

Explanation

**Step-by-Step Solution:**

1. **Identify the Phenomenon:**
The phenomenon responsible for the bending of light around sharp corners of an obstacle is called **diffraction**.

2. **Conditions for Diffraction:**
Diffraction occurs under specific conditions:
- The size of the obstacle or aperture (opening) must be comparable to the wavelength of the light being used. This means that the dimensions of the diffracting body should be on the order of the wavelength of light (approximately 400 nm to 700 nm for visible light).
