Summary of Event
The photoelectric effect was known to science in the early nineteenth century when Alexandre-Edmond Becquerel in France wrote of it in connection with his work on glass-enclosed primary batteries. He discovered that the voltage of his batteries increased with intensified illumination and that green light produced the highest voltage. Since Becquerel researched batteries...
