A newly formed protostar will radiate primarily at which wavelength?

Question

Quizplus · Accepted Answer

Protostars are very young stars that are still in the process of formation. At this stage, they are not hot enough to initiate nuclear fusion in their cores, which is the process that powers mature stars and causes them to emit light across the electromagnetic spectrum, including visible light. However, protostars do emit a significant amount of energy as they contract under gravity, and this energy is primarily released in the form of infrared radiation. This is because the material surrounding a protostar is dense and absorbs the higher energy radiation, re-emitting it as infrared.
