Heat is transferred from an electric bulb by
Conduction
Convection
Radiation
All options are correct
Radiation
Heat is transferred from electric bulb
mainly by radiation invisible range and hence we are able to see things where
bulb is switched ON.
Due to having very high temperature
difference between bulb and surrounding, that’s why radiation of bulb spread
all over thesurrounding.
Hence, the correct option is (C).
