A newly formed protostar will radiate primarily at which wavelength?

Question

Quizplus · Accepted Answer

A newly formed protostar is surrounded by a dense cloud of gas and dust, which is opaque to visible light and absorbs most of it. Infrared radiation, however, can pass through this material more easily and is therefore the primary wavelength that is emitted by a protostar. Over time, as the surrounding cloud dissipates, the protostar will emit more visible light. A newly formed protostar will radiate primarily in the infrared wavelength due to the high temperatures and dust surrounding the protostar. As the protostar continues to evolve and contract, it will eventually start emitting visible light.
