### Question: 
An electron, a proton and a neutron have the same de Broglie wavelength. Which statements is true?

### Options:
1. All particles have the same speed but different momentum.
2. The proton and neutron have the same speed and the same momentum.
3. The electron has the highest speed and the highest momentum of these three particles.
4. The neutron has the lowest speed.

### Actions:

### Description:
This question is designed to test your understanding of the de Broglie wavelength and its relationship with the speed and momentum of particles. The de Broglie wavelength, which is a fundamental concept in quantum mechanics, relates a wave property (wavelength) to a particle property (momentum) using the equation:

\[ \lambda = \frac{h}{p} \]

where:
- \( \lambda \) is the de Broglie wavelength,
- \( h \) is the Planck constant,
- \( p \) is the momentum of the particle.

Here, you are to determine the most accurately stated relationship among the electron, proton, and neutron given they all share the same de Broglie wavelength. Consider their masses and how these affect their speeds and momenta.
