Question

In the radiative zone, light particles called what can only travel a few millimeters before they hit another particle?

Answer 1

photons

The radiative zone is the next layer out. It has a temperature of about 4 million C. Energy from the core travels through the radiative zone. The energy travels at an extremely slow rate. Light particles are called photons . In the radiative zone, photons can only travel a few millimeters before they hit another particle. The particles are absorbed and then released again. It may take 50 million years for a photon to travel all the way through the radiative zone.
