Two objects (A and B) are placed on a table. Object A reflects red light and absorbs all other colors, while object B reflects green light and absorbs all other colors. What colors will the objects appear?

• Object A will appear red, and object B will appear green.

• Object A will appear black, and object B will appear white.

• Object A will appear white, and object B will appear black

• Object A will appear green, and object B will appear red.

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.
