Answer:The correct option is D.Explanation:The wavelength of the photon can be calculated with the following equation:

Where:

E: is the energy of the photon = 2.90 eV

h: is the Planck’s constant = 6.62×10⁻³⁴ J.s

c: is the speed of light = 3×10⁸ m/s

λ: is the wavelength

Hence, the photon’s wavelength is:Therefore, the correct option is D.I hope it helps you!
