Why does a white shirt appear white to the human eye?
The shirt absorbs all wavelengths of light in the visible portion of the electromagnetic spectrum.
The shirt absorbs light wavelengths at the red and blue ends of the spectrum but reflects colors in the middle of the spectrum.
The shirt reflects all wavelengths of light in the visible portion of the electromagnetic spectrum.
The shirt reflects light wavelengths at the red and blue ends of the spectrum but absorbs colors in the middle of the spectrum.
Which statement is true for an object that appears black when exposed to sunlight?
