Radiative energy
Step-by-step explanation:
The light from polaris travels through space in the form of energy is called
Radiative energy.
This energy is transferred by means of electromagnetic radiation like X-rays, gamma rays, light, heat radiation and so on. It can travel through space in the form of radiation. For instance, we get the heat through the sun, that is located far away from the Earth by means of radiation. Through the electromagnetic waves, sun's heat is transmitted and not through any kind of solid medium, but by means of vacuum.
