### Step-by-Step Solution:
1. **Understanding the Young's Double Slit Experiment**:
- In a typical Young's double slit experiment, two coherent light sources (or a single source passing through two slits) create an interference pattern on a screen. The pattern consists of bright and dark fringes due to constructive and destructive interference of light waves.
2. **Using White Light**:
- When white light is used as the source, it contains multiple wavelengths (colors). Each wavelength will create its own interference pattern, leading to a spectrum of colors on the screen.
