Alright. Let's bring our attention back. Strictly speaking, the photovoltaic effect doesn't have much direct connection to the wave theory, but it's an essential step that can't be ignored. First off, it's a mental transition, so those big shots don't suffer heart attacks from suddenly witnessing some phenomena, causing tragedy in the history of human science. Second, it's for... inspiring old Faraday. Don't forget, the concept of semiconductors was first proposed by Faraday. Look at him now, twitching like Wu Lao'er, if this were a fantasy novel, that'd be a textbook case of "sudden enlightenment," right? Shortly, several professors came over to the electrolytic cell, watching the phenomenon again. Stokes even went as far as to touch the platinum electrode, but snapped his finger back immediately. (Not recommended, by the way. The feeling is similar to getting shocked by a metal computer case, don't ask me how I know, just know I was stubborn back then.)
