Question

Why light sometimes changed a material and sometimes doesn’t?

Answer 1

When light falls on a material, the energy in its photons can affect the atoms in the material. In some materials, such as metal, the atoms absorb some of the photons so light does not pass through them. In other materials, such as glass, the atoms cannot absorb the photons and light passes through them.
