Reflection
Reflection is the change in the direction of light that, when coming into contact with the surface of separation between two changing media (such as a mirror, body of water, metal surfaces…), returns to the environment where it originated in the form of reflection.
Refraction
Light refraction is the change in the direction of light rays that occurs after passing these from one medium to another in which light propagates at different speed. This effect occurs at the entry of sunlight into the Earth’s atmosphere. Time and Date
