Answer:Frequency
Explanation:
The property of light that does not change when it travels from one medium to another is frequency, The energy of the light is related to the frequency; when the light enters the medium there are interference patterns that cause the apperent speed of light to change; if the frequency changed, the energy would not be conserved .Other properties of light like wavelength, speed of light changes when light travels from one medium to another.
