Answer 2

Radiation

• Radiation is defined as the emission and transmission of power in form of waves over space or even a material substance.
• Based on the energy of radiated particles, radiation is frequently classified as ionizing or non-ionizing.

Radiant Heat

• The conversion of electromagnetic radiation that characterizes the heat energy exchange by a photon is called radiant heat, also referred to as thermal radiation.
• Radiant heat is just a heat exchange technique that does not need a medium to spread.
