Mirrors reflect heat
The color of a material affects heat radiation by influencing the material's ability to absorb and reflect heat. Darker colors absorb more heat because they absorb a wider range of wavelengths, while lighter colors reflect more heat because they absorb less energy from the sunlight. Ultimately, the color of a material impacts its temperature and how it interacts with its environment.
Light colours. White is best.
Light colors such as white and silver are the best at reflecting heat because they reflect most of the sunlight that hits them. Dark colors, like black, absorb more heat because they absorb most of the sunlight.
white. they reflect lightwaves containing heat the best.
Silver is a highly reflective material, so it will mostly reflect heat rather than absorb it. This property makes silver a good choice for applications where heat reflection is important, such as in window films or reflective coatings.

Wood. Is the best material to use to seperate heat from cold.
The best heat insulator is a material with low thermal conductivity, such as aerogel, fiberglass, or polyurethane foam. These materials are effective at reducing heat transfer by minimizing the movement of heat energy through the material.
When light enters a material and does not pass through or reflect, it is absorbed. This allows the material to convert the light's energy into other forms, such as heat or electrical energy. The absorbed light excites electrons in the material, leading to various optical and chemical effects.
Metals.
Electricity does not conduct heat. Your question is meaningless.
Black marble will reflect less radiant heat compared to white marble, as black surfaces tend to absorb and retain more heat. White marble will reflect more radiant heat due to its lighter color and higher albedo, which limits heat absorption.
