What is the principle behind photoelectric transducers?(a) conversion

1.	What is the principle behind photoelectric transducers?(a) conversion of wind energy to electrical energy(b) conversion of light energy to electrical energy(c) conversion of mechanical energy to electrical energy(d) conversion of electrical energy to light energyThis question was addressed to me in class test.This is a very interesting question from Photoelectric Transducers topic in division Physiological Transducers of Biomedical Instrumentation
Answer» Right answer is (b) conversion of light energy to ELECTRICAL energy The best I can explain: Photoelectric transducers are based on the principle of conversion of light energy into electrical energy. This is done by causing the radiation to FALL on a photosensitive ELEMENT and measuring the electrical CURRENT so GENERATED with a sensitive galvanometer directly or after suitable amplification.
