Light is emitted when an electron
A)is boosted to a higher energy level.
B)makes a transition to a lower energy level.
C)accelerates to a medium energy level.
D)none of the above

Question

Quizplus · Accepted Answer

When an electron undergoes a transition from a higher energy level to a lower energy level, it releases energy in the form of light. This is known as emission of light. Therefore, option B is the correct choice. Option A is not correct because the emission spectrum occurs when electrons drop from higher energy levels to lower energy levels. Option C is not correct because acceleration of electrons does not cause the emission of light. Option D is also not correct because option B is a valid answer.
