Light travels in a straight line.
Light reflects off of shiny, smooth and bright surfaces.
Light waves come from the sun and other sources. Lots of other types of waves come from the sun and other stars. Those other waves can't be seen by our human eyes. We can only detect wavelengths that range from 400-700 nanometer, which is visible light. The range of waves that come from the sun is called the electromagnetic spectrum.
