For an orbital angular momentum quantum number of 4, what is the magnitude of the orbital angular momentum? A) 4ℏ B) 3ℏ C) 6^1/2ℏ D) 12^1/2ℏ E) 20^1/2ℏ

Question

Quizplus · Accepted Answer

The magnitude of the orbital angular momentum is given by L = √(l(l+1)ℏ), where l is the orbital angular momentum quantum number. For l = 4, L = √(4(4+1)ℏ) = √(20ℏ) = √(4*5ℏ) = 2√5ℏ. Therefore, the correct choice is E, which is 20^1/2ℏ.
