If travelling at same speeds, whichof the following mater waves have the shortest wavelength?

Options

A. Electron
B. Alpha partice `(He^(2+))`
C. Neutron
D. Proton

Explanation

To determine which of the given matter waves (electron, alpha particle, neutron, or proton) has the shortest wavelength when traveling at the same speed, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Wavelength Formula**:
The wavelength (λ) of a matter wave can be calculated using the formula:
\[
\lambda = \frac{h}{p}
