Which of the following is not a charcleristic both as an motion and as a stream of particles?

Options

A. Interference
B. `E = mc^(2)`
C. Diffraction
D. `E = hv`

Explanation

To solve the question "Which of the following is not a characteristic both as a motion and as a stream of particles?", we need to analyze the characteristics of particles and waves, particularly in the context of quantum mechanics.

### Step-by-Step Solution:

1. **Understanding Particle Motion**:
- Particles, such as photons, exhibit both particle-like and wave-like properties. This is known as wave-particle duality.
- As particles, they can be thought of as discrete packets of energy (quanta) that have mass and momentum.
