What is a particle or matter wave and how it is different from electro-megnetic wave?

Explanation

### Step-by-Step Solution:

1. **Definition of Particle or Matter Wave**:
- A particle or matter wave refers to the wave-like behavior exhibited by particles, such as electrons and atoms, as described by quantum mechanics. This concept is rooted in the de Broglie hypothesis, which states that every moving particle or object has an associated wave.

2. **Definition of Electromagnetic Wave**:
- Electromagnetic waves are waves of electromagnetic radiation that propagate through space. They consist of oscillating electric and magnetic fields and can travel through a vacuum. Examples include visible light, radio waves, X-rays, etc.
