Sparkles Sometimes on a sunny day, freshly fallen snow may appear to sparkle, or glitter.
Reflection takes place at the boundary of the object.
The reason we see many of the objects around us is because light is reflected off the object and toward our eyes. Sometimes the object only reflects, or transmits, a certain color. For example, clear water transmits all light, yet it can also act like a mirror. Think of how a calm lake can reflect an image of the surrounding trees. You can demonstrate this effect by filling a bowl, or sink, with water and looking straight down from above.
