When light waves travel from one medium (air) to the next (water), their velocity changes. Does their frequency change also? Or does the wavelength change?

Homework Help Overview
The discussion revolves around the behavior of light as it transitions between different mediums, specifically focusing on changes in velocity, frequency, and wavelength. The subject area pertains to optics and wave behavior.
Discussion Character
- Exploratory, Conceptual clarification
Approaches and Questions Raised
- Participants explore the relationship between frequency, wavelength, and velocity of light as it moves from air to water. Questions are raised about whether frequency changes and how this relates to the separation of colors in a prism.
Discussion Status
The discussion is active, with participants providing insights and clarifications about the properties of light. Some guidance has been offered regarding the constancy of frequency and the implications for light behavior at interfaces.
Contextual Notes
There is an underlying assumption that participants are familiar with basic wave properties and the concept of light interacting with different mediums. No specific constraints or rules are noted in the discussion.

hi gkangelexa! 
the frequency stays the same
the frequency stays the same
(otherwise they wouldn't "join up" properly at the interface 
)

Doesn't white light, upon entering a prism, break into colors according to frequency?

Hi Steve!
Yup, but the colours are already there (as good ol' Sir Isaac showed) …

) …the colours stay the same, but their speeds change, so they go through at different angles, and become separated.
