Anna studies the color of her bedroom wall using different lights. In sunlight, she sees that the wall is white.
Then she gets an idea for an experiment. Anna darkens the room and shines a beam of light that includes all the wavelengths of visible light onto the wall.
In this light, the wall appears <em>white</em>. (Choiced)
Anna will see aw white light on the wall. This is possible for a simple reason: Light, as we see it is a mixture of lights of different wavelengths. The different wavelengths mix and merge to give light that appears to be monochromatic - meaning of one wavelength. This single wavelength light is also of a single color. Inadvertently, the light will appear to be white.

The answer is C. ionic compounds, compared to another hard compound which is the covalent bond, the structure of the ionic compound is lattice or crystalline in form thus less room for imperfections on its structure compared to the latter choices.
