Suppose `10^(-17)` J of light energy is needed by the interior of the human eye to see an object. How many photons of green light`(lamda=500nm)` are needed to generate this minimum amount of energy?

Explanation

To solve the problem of how many photons of green light (with a wavelength of 500 nm) are needed to generate an energy of \(10^{-17}\) J, we can follow these steps:

### Step 1: Calculate the energy of a single photon
The energy \(E\) of a single photon can be calculated using the formula:
\[ E = \frac{hc}{\lambda} \]
where:
