The discussion centers on the behavior of monochromatic light as it transitions from a denser medium to a rarer medium. It establishes that while the wavelength of light changes during this transition, the perceived color remains unchanged due to the constancy of frequency across media. The conversation highlights the importance of frequency over wavelength in determining color perception, particularly in applications such as ophthalmology. Participants emphasize that the retina's environment ultimately dictates the wavelength that reaches the observer's receptors.

Thank you for sharing the link. In that thread a light ray just goes from a rarer medium to a denser and back to the same rarer medium so the wavelength of the light at the start and end is the same and there is no difference in the color of the original light. My question is different as light passes from denser to rarer so the wavelength received by observer will be different. shouldn't that make the original color of an object in the denser medium different from what is received?DrClaude said:
One reason for this question, at least that's been why I was interested in, are applications in ophthalmology. Being someone who has been lasered a few times it was an interesting answer.nasu said:But even if it were dependent of wavelength (hypothetically), then why would you care about the wavelength in that medium or in any other medium?
