Particle Wavelength Comparison
This simulation demonstrates the de Broglie wavelength comparison from Example 11.6, showing how a particle moving 3× faster than an electron with a wavelength ratio of 1.813×10⁻⁴ must have the mass of a proton or neutron.

Particle Wavelength:
1.32 × 10⁻¹³ m
Wavelength Ratio (λₚ/λₑ):
1.813 × 10⁻⁴
Calculated Particle Mass:

Particle Identification
The calculated mass of 1.675 × 10⁻²⁷ kg matches the known mass of:
- Proton: 1.673 × 10⁻²⁷ kg
- Neutron: 1.675 × 10⁻²⁷ kg
This confirms the particle is either a proton or neutron, as shown in Example 11.6.
