Which one of the following series of lines in the hydrogen spectrum arises from transitions down to n = 2?
A) 121, 102, 97, 95 nm
B) 655, 485, 433, 409 nm
C) 1872, 1279, 1092, 1003 nm
D) 4044, 2620, 2162, 1941 nm

B) 655, 485, 433, 409 nm

Explanation:

655, 485, 433, 409 nm

The greater the energy change involved in a transition, the shorter the wavelength.

Transitions to n = 2 from n = 3, 4, 5 and 6 give lines of wavelength 655, 485, 433 and 409 nm. Other answer choices represent the Lyman. Brackett, and Pfund series.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
