Why black colour absorb more heat than others
Answers
Given a material of a certain chemical/physical composition, colors get their "colors" from the electromagnetic spectrum they reflect from a light source. The basic colors Red, Green, Blue composes White light. So, the closer the "color" to white, the more light energy it reflects. The darker the "color" (closer to black), the more energy is absorbed. In terms of color, black is actually, the absence of light. In this case, the absence of reflected light.
Absorbed light energy is transformed to Heat energy, hence, lighter colors is better on summers. Darker colors is better suited on winters.
Our eyes are sensitive to light which lies in a very small region of the electromagnetic spectrum labeled "visible light". This "visible light" corresponds to a wavelength range of 400 - 700 nanometers (nm) and a color range of violet through red. The human eye is not capable of "seeing" radiation with wavelengths outside the visible spectrum. The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum. Black is a total absence of light.
Earth's most important energy source is the Sun. Sunlight consists of the entire electromagnetic spectrum.
Black objects absorb all wavelengths of light and convert them into heat . That's why black colour absorb more heat than others...
