mechanical energy to nuclear energy thermal energy to chemical energy kinetic energy to potential energy radiant energy to electrical energy
I gave my students this multiple choice question: Which of these processes is a conversion made by solar panels?

Only one answer is correct among these 4 choices:
- mechanical energy to nuclear energy
- thermal energy to chemical energy
- kinetic energy to potential energy
- radiant energy to electrical energy

Could you tell me which one is correct?

radiant energy to electrical energy
