The main difference between Reflection and Dispersion: Reflection is the bouncing back of light from a smooth surface without change in wavelength. Dispersion is the splitting of white light into its component
Reflection vs Dispersion — Comparison Table
| Basis | Reflection | Dispersion |
|---|---|---|
| Definition | Light bounces back from surface | Light splits into component colors |
| Wavelength | Wavelength remains unchanged | Different wavelengths separate |
| Surface Type | Occurs on smooth surfaces | Occurs in prisms or water droplets |
| Direction | Light returns at specific angle | Light separates into different directions |
| Causes | Smooth surface bounces light back | Refractive index variation with wavelength |
| Result | Mirror image or reflected light | Rainbow or spectrum of colors |
Key Points
- Reflection follows the law of reflection
- Dispersion depends on the material's refractive index for different wavelengths
- Both can occur together when light hits a prism
- Rainbows are formed by both reflection and dispersion in water droplets
