The discussion centers on the behavior of light waves as they propagate through different media, specifically addressing whether the wavelength, frequency, or both change when the velocity of light is reduced compared to its speed in a vacuum. The scope includes conceptual understanding of wave properties and their relationships.
Participants do not reach a consensus; there are competing views regarding whether frequency changes or remains constant alongside wavelength when light travels through a medium.
Unresolved assumptions about the definitions of frequency and wavelength in different media, as well as the implications of changing speed on these properties, are present in the discussion.
LostConjugate said:The frequency does not change. The wavelength does.
Only if you keep the speed constant, which is not the case here. What is true, is that speed = freq X wavelength. Both speed and wavelength decrease.agentas said:but how it can be .if you reduce wavelength your frequency becomes bigger.
