What are the properties that make materials reflect or absorb a certain EM wave or just allow it to pass through ( transparency ) ??
Thanks a lot for guiding me " smile " but I don't think I could find an answer for my question thereZapperZ said:Start by reading the General Physics FAQ subforum.

The title "Do Photons Move Slower in a Solid Medium?" Does not show the relevance but the article actually shows.ZapperZ said:Does that mean that you read this and didn't see the relevance?

Really?

Reflection is the bouncing back of light, sound, or heat off of a surface. It occurs when the surface is smooth and shiny, allowing the light to bounce off at the same angle it hit the surface.
Transparency is the property of allowing light to pass through a material without scattering or absorbing it. This is typically seen in materials that are clear, such as glass or water.
Absorption is when light, sound, or heat is taken in and not reflected or transmitted. This can happen when the surface of a material is rough or dark, causing the energy to be converted to heat.
Reflection and absorption affect the color of an object. Objects that appear white reflect all colors of light, while objects that appear black absorb all colors. Translucent objects appear to have a color because they both reflect and transmit light.
Reflection, transparency, and absorption have many practical applications in everyday life. For example, the reflective properties of mirrors are used in bathrooms and dressing rooms, while the transparency of glass is used in windows and eyeglasses. Absorption is utilized in solar panels to convert sunlight into energy. These properties also play a role in photography, art, and design.
