Question 5 4 pts 5) What is the wavelength of light emitted when the electron in a hydrogen atom undergoes a transition from level n = 8 to level n = 2 (emission)? |DeltaE] = RH [1/n12 - 1/n221, where c = 3.00 x 108 m/s, h = 6.63 x 10-34 Jos, RH = 2.179 x 10-18J). Delta E = hc/Lamda, 0 537 nm O 197 nm O 389 nm 393 nm 423 nm
