Oh wait, I think the OpenStax textbook just assumed an efficiency equal to 1.
Many thanks!

Graphing Power vs Polarizer Angle using Intensity
Click For Summary
Homework Help Overview
The discussion revolves around graphing power versus polarizer angle using intensity measurements from an experiment involving a laser and polarizers. Participants are exploring how to derive transmitted power from recorded intensity values, which are measured in lux, and are questioning the relationship between intensity and power in this context.
Discussion Character
- Exploratory, Conceptual clarification, Assumption checking
Approaches and Questions Raised
- Participants are attempting to understand how to calculate transmitted power from transmitted intensity and whether to consider the area of the polarizer in their calculations. There are discussions about the implications of negative intensity readings and the relationship between intensity and power, particularly in terms of proportionality.
Discussion Status
The conversation is ongoing, with participants sharing data and clarifying their understanding of the relationships between intensity, power, and polarizer angles. Some participants have provided guidance on how to approach the graphing of power versus polarizer angle, while others are still questioning the assumptions and definitions involved in their calculations.
Contextual Notes
There are constraints regarding the availability of certain measurements, such as the area of the polarizer and the maximum power of the laser, which are affecting the ability to graph power versus polarizer angle accurately. Participants are also addressing potential errors in their data collection and the definitions of the angles involved in the experiment.
