Final answer:
When light passes through a window, the transmitted light does not have a phase shift with respect to the incident light.
Step-by-step explanation:
When light passes through a window, the transmitted light does not have a phase shift with respect to the incident light. This means that the phase of the transmitted light is the same as the phase of the incident light.
This is because the window is a transparent medium, and when light passes from one transparent medium to another, there is no change in phase of the light. The speed of light may change due to the different refractive indices of the media, but the phase remains the same.
