What Is A Radiation? (Heat Transfer)

    Could anyone please illustrate me about radiation by an illustration?

    If don't mind, animation could be great.

    The IR part of sunlight(mostly) carries heat. That is radiation.

    IR is infra-red

    Actually, ALL "light", visible to the human eye or not, is radiation. Radio waves are radiation. The entire electromagnetic spectrum is radiation.

    This is such a basic concept that you should just poke around with Google.
