Question

Radiation transfers energy by waves. These waves transfer energy from a warmer object to a cooler object, with or without

Answer 1

They transfer the energy with or without medium
Since radiation is transferred through wave, it does not need any form of objects to pass through.
For example, the heat that radiation through the sun could be felt without any objects that connect us from The sun itself.

Answer 2

The corrects answers are “Thermal”, “electromagnetic”, and “matter”.

Radiation transfers thermal energy by electromagnetic waves. These waves transfer energy from a warmer object with or without matter.

When talking about physics, Electromagnetic waves (EM) are created due to the vibration of a magnetic field and electric field. The composition of Electromagnetic waves are of electric fields and oscillating magnetic. These waves are formed when the magnetic field is in contact with the electric field. Among the electromagnetic waves that we found in daily life, we have the gamma ray, infrared waves, microwave, x-rays, radio waves.
