We feel the heat from the stovetop because of radiation.
Convection:
It is the process by which heat is transferred because of the movement of a heated fluid. for example air or water.
Radiation:
It is the emission of energy in the form of waves or particles through space or through a medium. such as air, etc.
In this case, if a stovetop is hot, and if you place your hand near the top of the stove and feel that it is warm without touching it.
We can feel the heat from the stovetop because of the radiation,
If we have our hand on the exact top of the stovetop then the heat from the stovetop would have been because of the Convection, as the fluid(air) would have been rising because of its own heating and getting the fluid density low causing it to rise as a result of the increased buoyancy.
But, as the hand is near the top of the stove, and as we feel warm without touching it. This is due to radiation, the heat is transferred due to the vibration of the air particles.
Hence, We feel the heat from the stovetop because of radiation.
