Final answer:
When white light passes from air into a different medium, it is refracted (bent) due to the change in the medium's refractive index.
Step-by-step explanation:
When white light passes from the air into a different medium such as glass, it is refracted (bent). This means that the light waves change direction as they enter the glass due to the change in the medium's refractive index. The speed of light also changes when it enters a different medium, causing the light to bend.
