Discussion Overview
The discussion centers on the feasibility of calculating the temperature of still water using Planck's Blackbody Radiation principles. Participants explore the theoretical and practical aspects of this calculation, including the role of emissivity and potential complications in measurement.
Discussion Character
- Exploratory, Technical explanation, Conceptual clarification
Main Points Raised
- One participant questions whether the temperature of still water can be calculated using blackbody radiation principles, specifically referencing an intensity image of the water.
- Another participant suggests that it might be possible to calibrate an infrared thermometer against a regular thermometer, but expresses skepticism about various factors that could affect accuracy, such as angle of incidence and container effects.
- A follow-up question asks if it is theoretically possible to perform such a calculation.
- A later reply affirms that it is theoretically possible to calculate the temperature, provided that emissivity is known as a function of wavelength and temperature, and that the water is deep enough to ensure a long enough path length.
Areas of Agreement / Disagreement
The discussion does not reach a consensus, as participants express differing views on the practicality and theoretical aspects of calculating the temperature of still water using blackbody radiation principles.
Contextual Notes
Participants note potential limitations related to emissivity, measurement conditions, and the assumptions required for accurate calculations.
