A photon and an elecron have the same de Broglie wavelength. Which has greater total energy? Explain

Explanation

To determine which has greater total energy between a photon and an electron that have the same de Broglie wavelength, we can follow these steps:

### Step 1: Understand de Broglie Wavelength
The de Broglie wavelength (λ) is given by the formula:
\[ \lambda = \frac{h}{p} \]
where \(h\) is Planck's constant and \(p\) is the momentum of the particle.
