Quizplus · Accepted Answer

The crystal field splitting energy (Δo) can be calculated using the formula Δo = 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 (700 nm or 700 x 10^-9 m). Substituting these values gives Δo = 2.84 x 10^-19 J, which matches option A.
