Calculate the energy of a photon of blue light, `lambda`=450 nm in air (or vacuum).

Text Solution

AI Generated Solution

To calculate the energy of a photon of blue light with a wavelength of \( \lambda = 450 \, \text{nm} \), we can use the formula for the energy of a photon: \[ E = \frac{hc}{\lambda} \] where: - \( E \) is the energy of the photon, ...
