Using the equation E = hc/λ, where h is Planck's constant (6.626 x 10^-34 J s), c is the speed of light (3.00 x 10^8 m/s), and λ is the wavelength in meters, we can find the energy in a single photon:
E = hc/λ = (6.626 x 10^-34 J s) x (3.00 x 10^8 m/s) / (1100 x 10^-9 m)
E = 1.81 x 10^-19 J
Therefore, the energy in a single photon of light with a wavelength of 1100 nanometers is a. 9.9 x 10^-32 J.
