Discussion Overview
The discussion revolves around an experiment designed to investigate how colored light affects the temperature of water. Participants explore the feasibility of measuring the energy absorption of different wavelengths of light by water and the implications for temperature change.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant suggests using a colored frame in front of a light source to shine on a beaker of water and proposes using a data logger to record temperature changes over time.
- Another participant clarifies that the experiment would measure the absorption of specific wavelengths of light by water rather than the energy contained in the photons.
- A participant mentions using the specific heat capacity formula to calculate energy based on temperature change, mass, and specific heat capacity of water.
- One reply supports the use of the specific heat capacity formula, assuming no energy loss to the surroundings, and notes it measures energy absorbed by the water.
- Another participant raises a concern that much of the light will pass through the water, suggesting the use of a solid, non-reflective material instead or proposing an alternative experiment like the photoelectric effect.
- One participant expresses skepticism about the experiment's potential to register a significant temperature change in water due to its absorption characteristics.
Areas of Agreement / Disagreement
Participants express differing views on the effectiveness of the proposed experiment, with some supporting the methodology while others question the expected outcomes and suggest modifications. There is no consensus on the feasibility or expected results of the experiment.
Contextual Notes
Participants acknowledge potential limitations such as energy loss to the surroundings and the inherent properties of water regarding light absorption. The discussion does not resolve these issues.
