Cotton is typically considered a dull fabric. It has a natural matte finish due to its fibers and weave structure, which give it a soft and comfortable feel.
A dull surface is a better absorber of infrared radiation heat compared to a shiny surface. The rough texture of a dull surface allows for more absorption of infrared radiation, while a shiny surface reflects much of the radiation.
No, dull silver surfaces may emit less radiation than shiny white surfaces because the reflectivity of a material affects its ability to absorb and emit radiation. Shiny white surfaces reflect more radiation compared to dull silver surfaces that may absorb and emit more radiation.
A dull surface would be a better absorber of light because its rough texture allows for greater light absorption due to increased surface area and multiple reflections within the material. Shiny surfaces reflect more light and are therefore poorer absorbers.
