Question

We see words on a page because light bounces off the page. What property of light is responsible or this?

Answer 1

Light hits the page and is absorbed by the atoms forming the paper and ink. This "excites" the electrons in those atoms to a higher energy level. As the electrons drop back down to a lower energy level they release light energy. This is the mechanism of "reflection". Different materials absorb and emit light of different wavelengths and so you perceive different colors.

Answer 3

The property of light is reflection. We get colours because of which frequencies of visible light are reflected. For example, if something is blue, it is absorbing all the frequencies apart from blue, which it reflects. If something is white, it reflects all frequencies. If something is black, it absorbs all frequencies.

And to go further, the reflected rays enter your eyes through the pupils, and are focused onto the retina by the lens. The cells of the retina then convert the light into a signal, which is sent to the brain via the optic nerves and turned into an image by the visual cortex - which is at the back of the brain.

Answer 4

Well, we only see *anything* because of the reflection of light from it's surface.  If there is no light, we don't see it.  

Any features, such as letters on a page, we see only because the light is reflecting differently (more or less strongly) from those sections than from others.

Answer 5

In the terms of your question, the simple answer is that light is composed of massless photons which have particle-like and wave-like properties.

The reflection of light is not due to photons behaving as particles and bouncing off the page, it's due to their wave-like properties causing them to be reflected.
