This is a follow-up question to Question #247, also using the thermopile. This week we will move the thermopile from the red region into the blue region and investigate how the indicator frequency changes. Note that we are moving into a region where the photon energy is higher.
So here is the final question for this topic. Suppose that again we start the thermopile in the red spectral region, but this time move it toward the blue end of the spectrum.
The frequency of the oscillator will:
