Explain how an electric light bulb can transfer heat in each of the following ways?

Question

Convection, radiation, and conduction.

Answer 1

convection - the glass is hot, air against it is warmed and rises being replaced by cooler air which heats etc etc
radiation - the light is in a frequency which radiates heat out from the hot tungsten filament. Place your hand a short distance away from the bottom (so you do not feel convected heat) and you can feel the radiated heat
conduction - as the glass warms, heat spreads all over. The metal base will also get hot by conducted heat through the filament-supporting wires inside the bulb
