Visible light has wavelengths in the range of 400 nm to 780nm. Calculate the range of energy of the photons of visible light.

Explanation

To solve the problem of calculating the range of energy of the photons of visible light with wavelengths from 400 nm to 780 nm, we can follow these steps:

### Step 1: Understand the Energy-Wavelength Relationship
The energy of a photon is inversely proportional to its wavelength, given by the formula:
\[ E = \frac{hc}{\lambda} \]
where:
- \( E \) is the energy of the photon,
- \( h \) is Planck's constant (\( 6.626 \times 10^{-34} \, \text{Js} \)),
