Discussion Overview

The discussion revolves around the effects of shining monochromatic light on a red strawberry after refracting sunlight through a prism to create a visible spectrum. Participants explore the implications of using different colors of light on the appearance of the strawberry.

Discussion Character

  • Exploratory, Conceptual clarification, Debate/contested

Main Points Raised

  • Some participants propose that a red strawberry appears red because it absorbs all colors except red, which it reflects.
  • There is speculation that under blue monochromatic light, the strawberry would appear black, as it does not reflect blue light.
  • One participant suggests that testing this idea would require placing the strawberry in a dark environment while shining the colored light on it, raising questions about the feasibility of such an experiment in open space.

Areas of Agreement / Disagreement

Participants generally agree on the absorption and reflection properties of the strawberry, but there is uncertainty regarding the experimental setup and the outcome under different colored lights.

Contextual Notes

The discussion does not resolve the practical aspects of conducting the experiment or the specific outcomes of the strawberry's appearance under different colors of light.

What would happen if I use a prism to refract the light from the sun into the visible spectrum and put a RED strawberry in the different colors?

For example if I put the strawberry over the Blue color what would happen?

What do you think would happen? Why does a strawberry look red when white light is shined on it? :smile:
 
Well the simple answer I think is because it absorbs all colors and reflects red?

So if I put it under blue monochromatic light it will appear black? I think?

Yep. :smile:

I want to test this out but for this to work using a prism and sun light I would have to put the strawberry in a dark place and shine the color on it?

And this probably wouldn't work if I try doing it in open space?
 
Thats neat! Thanks!
