How does light travel?
the light moves in straight waves
Why can we see objects?
it is for the reflection, becuase when the light waves hit an object, they bounce off of it, For most objects, the light bounces in many directions at the same time. When this happens, it allows us to see the object.

How do light waves act when they hit a smooth or shiny surface?
Anything shiny surface may act like a mirror when the light hits it and in the smooth  surfaces may not act like a mirror.

Will a lake filled with people boating and swimming act like a mirror? Why, or why not?
In my opinion I do not belive that the surfaces of the lake in this situacion may act like a mirror, beacuase need more light of sun for that the water reflect all in the lake.

The ability of glass to refract light has given us some useful products. Eyeglasses help us see clearly. Magnifying glasses enlarge our view of an object..
