• A) \(3.09 \mu \mathrm { m }\)
• B) \(133 \mathrm {~nm}\)
• C) \(241 \mathrm {~nm}\)
• D) \(354 \mathrm {~nm}\)
• E) \(2.11 \mu \mathrm { m }\)

Definitions:

NREM-3

The third stage of non-rapid eye movement sleep, characterized by deep sleep and the presence of delta waves.

N2 Sleep

A stage of sleep characterized by specific brain wave activity known as sleep spindles and K-complexes, marking a deeper sleep phase than N1.

N3 Sleep

The deepest stage of non-REM (Rapid Eye Movement) sleep, characterized by delta waves and significant physiological changes that contribute to physical recovery and health.

REM Sleep

A phase of sleep characterized by rapid eye movements, dreaming, and increased brain activity.
