Hint: When a colour absorbs light, it turns the light into thermal energy (heat). The lighter a colour absorbs, the more thermal energy it produces. Dark colours absorb more heat compared to lighter colours.
Complete step by step answer:
A black colour object absorbs all wavelengths of light and reflects none. Therefore, black colour objects will absorb more heat. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.
Our eyes are sensitive to light which lies in a very small region of the electromagnetic spectrum labelled "visible light". This "visible light" corresponds to a wavelength range of 400 - 700 nanometres (nm) and a colour range of violet through red. The human eye is not capable of "seeing" radiation with wavelengths outside the visible spectrum. The visible colours 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 colours 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.
So, the correct option is B.
Note:
Absorbed light energy is transformed to Heat energy, hence, lighter colours are better in summers. Darker colours are better suited on winters.
