You can see your reflection in a window because glass is smooth and acts like a mirror, reflecting light that hits it. When light from your face hits the window, it bounces off and creates your reflection.
No, but it can reflect light which can easily turn into heat when it hits something.
When light hits an object, it can be transmitted (pass through the object), absorbed (taken in by the object), or reflected (bounced off the object). The color of the object we see is the result of the wavelengths of light that are reflected off the object and into our eyes.

When the beam hits the front it of something like a prism again & again & emerges from the drop of rain water we see the color spectrum that's in a rainbow. The water drop acts like a prism to separate the light into its different wave lengths.

Reflection refers to the bouncing back of light when it hits a surface such as a mirror. This is how we are able to see objects in our surroundings, as they reflect light rays into our eyes for us to perceive them visually.
Because the Shadow is also dependent on the angle of the light source compared to the opaque object.
Usually when light hits a piece of glass or plastic the light 'bends' towards something called its 'normal' which is basically just a straight line through any object (must be at a right angle).
No limit ... even across the universe ... until it hits something that absorbs it. Astronomers regularly capture images formed by light that has traveled for about 14 billion years before it hits the film or CCDs in their telescopes and stops. In that amount of time, the light has traveled something like 82,296,200,000,000,000,000,000 miles. (rounded to the nearest hundred quadrillion miles)
