Question

light from a lamp is an example of a transfer of thermal energy by
convection
expansion
radiation
conduction

Explanation:

Thermal energy transfer by radiation occurs through electromagnetic waves. Light from a lamp travels as electromagnetic waves (infra - red and visible light), which is a form of radiation. Convection involves the movement of fluids (liquids or gases). Expansion is a property related to temperature change causing a substance to increase in volume. Conduction is the transfer of heat through direct contact between materials.

Answer:

radiation
