Question

We can see *Response area* objects because light *Response area* are altered by the objects. Unless an object is perfectly transparent, a little of the light bounces off by the property of *Response area.* Most of the light *Response area* bends by the property of *Response area* as it passes through a clear object. For example, when you look at a glass, *Response area* bends the light as it passes through the glass and the background image ends up changed. Your *Response area* interprets the rays reaching your eye. It determines the shape of the cup by how the background image is distorted.
