Light is

Options

A. wave phenomenon
B. particle phenomenon
C. both particle and wave phenomenon
D. none of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Nature of Light:**
- Light exhibits characteristics of both waves and particles. This dual nature is a fundamental concept in physics.

2. **Wave Behavior of Light:**
- When light travels through different media (like air to water), it demonstrates wave properties such as refraction, diffraction, and interference. These phenomena are typical of wave behavior.

3. **Particle Behavior of Light:**
- In certain experiments, light behaves as if it is made up of discrete packets of energy called photons. Each photon carries a specific amount of energy, which is indicative of particle behavior.

4. **Conclusion:**
- Since light exhibits both wave-like and particle-like properties depending on the context, we conclude that light is both a wave phenomenon and a particle phenomenon.

5. **Final Answer:**
- Therefore, the correct option is C: both particle and wave phenomena.
