what happens when light strike a dark table?
the tables becomes warm
It gets absorbed at or near the surface of the table and turns to heat energy.
When light strikes a dark table, several things can happen depending on the properties of the table surface.
1. Absorption: If the table is made of a material that absorbs most of the light, such as a black or dark-colored material, then the light will be absorbed by the table. The energy of the light will be converted into heat energy within the table material, causing it to warm up.
2. Reflection: Some of the light may be reflected off the table surface. Reflection occurs when light rays bounce back off a surface without being absorbed. The angle at which the light hits the table surface (angle of incidence) will determine the angle at which it reflects off the surface (angle of reflection).
3. Scattering: If the surface of the dark table is rough or uneven, the light may scatter in different directions. This can happen when the surface has microscopic bumps or imperfections. Scattering causes the light to spread out in various directions rather than being reflected in a specific direction.
4. Transmittance: If the table has a translucent or transparent portion, such as a glass tabletop, some light may pass through it. This phenomenon is called transmittance. The amount of light that passes through the table will depend on the transparency of the material and its thickness.
To observe and understand these effects, you can conduct an experiment. Place a dark-colored table in a well-lit room and observe how the light interacts with its surface. By closely examining the surface properties and material composition, you can gain a deeper understanding of what happens when light strikes a dark table.
