In short, because they "don't reflect'."
A matte surface isn't smooth; it has a surface that does not fully reflect light/radiation; the surface looks dull because there's little reflection.
A smooth surface will reflect because it's smooth (glass-like) and will reflect or bounce light away from its surface. The surface looks shiny because of the reflection.
The color of the surface matters because the darker the color, the more light/radiation is absorbed. Lighter colors reflect light; darker colors absorb light.
What else can I help you with?
What colors reflect radiant energy?
Colors like yellow, orange, and red reflect radiant energy. These colors have longer wavelengths and higher energy compared to other colors in the spectrum, allowing them to reflect more radiant energy.
If you know that a surface is a good absorber of energy what can you infer about its ability to radiate energy?
If a surface is a good absorber of energy, according to Kirchhoff's law of thermal radiation, it must also be a good emitter of energy. This is known as the principle of reciprocity. Therefore, if a surface can absorb energy efficiently, it will also radiate energy effectively. This relationship is crucial in understanding the behavior of objects in thermal equilibrium.
Which law governs the distribution of radiant energy over wavelength for a black body at fixed temperature?
The law that governs the distribution of radiant energy over wavelength for a black body at a fixed temperature is called Planck's law. It describes how the intensity of radiation emitted by a black body varies with wavelength at a specific temperature.
What colour is the best absorber of heat and why?
Matte black because it absorbs most wavelengths.
How does the color of something affect radiant energy?
The color of an object affects the amount of radiant energy it absorbs and emits. Darker colors absorb more radiant energy because they absorb more light, while lighter colors reflect more radiant energy. The color of an object can impact its temperature and heat absorption, making it an important consideration in energy efficiency and thermal management.

Two things that absorb the sun's radiant energy?
Solar panels: Solar panels are designed to absorb the sun's radiant energy and convert it into electricity to power homes and buildings. Black asphalt: Dark surfaces like black asphalt absorb the sun's radiant energy effectively, which is why they can get very hot on a sunny day.
How is radiant energy different from energy of motion and stored energy?
Surprisingly there is little difference. radiant energy transfers watts through massless particles call photons. You could actually push a black sail with light if you had a light source bright enough. The only way to store radiant energy with only one conversion of energy is electrically into a battery; you could use a photovoltaic cell. Still, all forms of energy can be converted to another form.
Which color is the best absorber of heat?
Black is the best absorber of heat because it absorbs all colors in the visible light spectrum and converts them into heat.
What absorbs radiant energy?
Darker colours (ex. black, navy blue) absorb more radiant energy than light colours, like white. Also, it helps if the surface is dull (not shiny) and cold at the beginning, because cold things absorb more radiant energy.
Why utensils are painted black?
The utensils are painted black because black is a good absorber of heat
Can an object be both a good absorber and good reflector at the same time why or why not?
No, you can be both good and evil. This is the same concept. The object is either a good absorber or a good reflector, and can not be both. Black is a good absorber, white is a good reflector.
How can the knowledge that black absorbs radiant energy and white emits radiant energy be used in real life?
This knowledge can be used in building design to help regulate temperature. Painting roofs white can reflect sunlight and keep buildings cooler, while using black materials for solar panels can help them absorb more energy. Understanding how different colors interact with heat can also be used in designing energy-efficient clothing or materials.
