How does light interact with objects?

When a light wave encounters an object, they are either transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered depending on the composition of the object and the wavelength of the light.

What is an example of light interaction?

Other examples of light-matter interaction phenomena are diffraction, which happens when light hits an obstacle (or opening), such as diffraction of light going through a small hole, and refraction, which occurs when light goes from one medium to another, for example from air to water, Prof. Jonsson says.

What is smaller than light?

Subatomic particles are even smaller than light.

Atom is basically made up of Electrons and Nucleon. Nucleon is made by proton and neutron. Proton and Neutron are created by quark.

Why can't we see small objects?

Our eyes have limits, so we can't see extremely small objects without help. Certain tools, like magnifying glasses, microscopes and telescopes, magnify objects so we can see them. "Magnification" means making something appear bigger without actually changing its physical size.
