How many photons of lights having a wave length of `5000 A` are necessary to provide `1` Joule of energy?

Explanation

To find out how many photons of light with a wavelength of \(5000 \, \text{Å}\) (angstroms) are necessary to provide \(1 \, \text{Joule}\) of energy, we can use the formula for the energy of a single photon:

\[ E = \frac{hc}{\lambda} \]

Where:
- \(E\) is the energy of one photon,
