← ScienceWhich outcome arises when a photon's frequency remains constant while transitioning from empty space into a transparent, refractive medium?
A)Wavelength decrease due to refractive index✓
B)Speed increase matches refractive index
C)Energy increase fulfilling light-matter interaction
D)Momentum decreases; energy conservation prevails
💡 Explanation
Wavelength decreases because photons slow down within, a result of light-matter's interaction. This reduction occurs through refraction, a consequence of frequency constancy. Therefore, wavelength shortens proportional to the refractive index, rather than altering speed or energy independent of momentum change.
