Two technicians are discussing headlights. Technician A says that the electricity creates electromagnetic energy in the filament which illuminates the light. Technician B says that the electricity creates electrochemical energy in the filament which illuminates the light. Who is correct

Technician A only

Explanation:

Here we have electromagnetic energy is an energy form that is emitted from charged objects as electrical and magnetic waves with a capability to move through space as electromagnetic radiation.

Examples of electromagnetic energy and electromagnetic radiation includes, visible light, radio waves, X-rays, gamma rays and Sunlight

While electrochemical energy is the energy through which chemical energy is converted into electrical energy and electrical energy is converted into chemical energy. Electrochemical energy has to do with batteries, super and ultra capacitors and electrochemical cell.

Since the filaments electrical setup does not comprise of an electrochemical cell and light is not a form of chemical energy, therefore, technician A only is correct.
