infrared heat energy visible light energy chemical energy electrical energy
I gave my students this multiple choice question: Tonya plugged in a toaster. She placed two slices of bread in the toaster, pushed down the lever, and the heating coils glowed. She noticed that only one form of energy toasted the bread. Which form of energy was wasted in the process?

Only one answer is correct among these 4 choices:
- infrared heat energy
- visible light energy
- chemical energy
- electrical energy

Could you tell me which one is correct?

visible light energy
