If the enrgy of a frequency v is gives by `E = hv` where `h` is plank's constant and the momentum of photon is `p = h//lambda` where `lambda ` is the wavelength of photon , then the velocity of light is equal to

Options

A. `sqrt((E )/(p))`
B. `(E )/(p)`
C. `Exx p`
D. `((E )/(p))^(2)`

Explanation

To find the velocity of light using the given equations for energy and momentum of a photon, we can follow these steps:

### Step 1: Write down the equations
We have two key equations:
1. Energy of a photon: \( E = h\nu \)
2. Momentum of a photon: \( p = \frac{h}{\lambda} \)

### Step 2: Relate wavelength and frequency
