Find the ratio of kinetic energy of the particle to the energy of the photon . If the de Broglie wavelength of a particle moving with a velocity ` 2.25xx 10^(8) m//s ` is equal to the wavelength of photon .

Explanation

To find the ratio of the kinetic energy of a particle to the energy of a photon when the de Broglie wavelength of the particle is equal to the wavelength of the photon, we can follow these steps:

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