Infrared 700nm to 1mm
Step-by-step explanation:
- A protostar is a star which is very young and acquiring mass from its parental molecular cloud.
- When the gravity starts to attract the gases together into a ball, the protostar will form at this point. This process is called accretion. The gravitational energy will start heat the gas at the centre when the gravity pulls the gasses into the centre. This trigger the gasses to emit radiation.
- The warm clumb is known as a protostar. Gas clump forms a disk with the protostar at the centre. Other materials will combine and form other planets and stars.
- At 2000 -3000K, the protostar will become red with most of its energy will be in infrared.
