Calculate the wavelength of the light emitted by a hydrogen atom during a transition of its electron from the n = 4 to the n = 1 principal energy level. Recall that for hydrogen E_n = -2.18 * 10^-18 J(1/n²). A) 6.8 * 10^-18 nm B) 0.612 nm C) 82.6 nm D) 97.2 nm E) 365 nm

The energy difference between the levels is calculated using the formula ΔE = E1 - E4. The wavelength is then found using λ = hc/ΔE, where h is Planck's constant and c is the speed of light. This results in a wavelength of approximately 97.2 nm.
