does the reflection of light just reflect a science book for example. does it reflect a perfectly polished mirror.
Light reflects off any polished surface
The way which light reflects has a lot to do with angles and rays. having a polished surface is definitely a huge factor but there are other factors such the angle at which the book is placed.The amount if light which is shone but most importantly the layer with which the cover of the book is coated with.most of my books have an incredibly thin layer of plastic.Plastic is fairly decent material for reflecting light.
Hope that helps this completely irrelevant non curriculum based question.
