Question

a fire is burning in a fireplace. where is the radiation?
you can feel the heat from across the room.
you touch the warm bricks next to the fireplace.
heat is rising up from the chimney.

Explanation:

Heat transfer by radiation occurs when electromagnetic waves carry heat from a source. In the case of a fireplace, the heat you feel across the room is due to radiation. Touching warm bricks is conduction (heat transfer through direct contact), and heat rising up the chimney is convection (heat transfer through fluid movement).

Answer:

You can feel the heat from across the room.
