The work function `(phi_0)`, of a metal X, equals `3xx10^(-19)J`. Calculate the number (N) of photons, of light of wavelength 26.52nm, whose total energy equal W. Plank's constant `=6.63xx10^(-34)Js.`

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the relationship between energy, work function, and number of photons.
The total energy \( W \) can be expressed in terms of the number of photons \( N \) and the energy of each photon. The energy of a photon is given by the formula:
\[ E = h \nu \]
where \( h \) is Planck's constant and \( \nu \) is the frequency of the light. The total energy can also be expressed as:
