Homework Statement
I am doing a lab and need to understand how laser light from a HeNe laser goes into a Si photodiode connected to a lock in amplifier, which I believe is simply a device for measuring potential, works.
Homework Equations
The Attempt at a Solution
This lab was extremely simple, we shot a laser through a beaker of water with food die in it, the laser went through the beaker into an Si photodiode, which was connected to an instrument to measure voltage. What I do not understand is how the light produces a potential difference in the Si photodiode.
If anybody can provide an explanation or refer me to relevant literature, it would be of great help to me.
Thanks
