Types of Energy Transformations

How does the chemical energy within a battery become light energy when you turn the flashlight on?

• the chemical energy transforms into electrical energy, then into light energy

• the chemical energy transforms into heat energy, then light energy

• the chemical energy transforms into sound energy, then light energy
