Here is major reason that EM radiation needs to travel without medium: between the Earth and the Sun is considered a vacuum, therefore if EM radiation needed a medium to propagate then we would not receive the light from the sun, thereby ceasing alot of vital processes that occur on Earth as a result of interaction with light.
By radiation, mostly infra red, visible, and ultra violet EM radiation
EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.EM radiation is short for electromagnetic radiation. It is a wave in the electric and magnetic fields.

For example:* We use visible light to see * We use microwave radiation in a microwave oven * We use various types of electromagnetic waves for communication * The Sun's energy comes to us, mainly via EM radiation.

The electromagnetic (EM) spectrum is a name for different types of radiation. Most radiation comes from the sun. Want more info?
Heat radiation is mainly associated with infrared radiation.

The process used for the sun's heat energy to reach Earth is called thermal radiation. This electromagnetic radiation is caused by charged particles' motion in the Sun.
