Predict the color of each substance:a. A solid substance absorbs all the wavelengths of visible light that strikes it.

When a solid substance absorbs all wavelengths of visible light, it does not reflect any light back to the observer. This results in the substance appearing black.

Explanation:

1. Absorption of Light: A substance that absorbs all visible light essentially takes in all the colors of the spectrum (red, orange, yellow, green, blue, indigo, and violet).

2. Color Perception: The human eye perceives colors based on the wavelengths of light that are reflected off an object. If an object reflects only certain wavelengths and absorbs others, the reflected wavelengths determine the color we see.

3. Resulting Color: Since this substance does not reflect any visible wavelengths, the result is total absorption, leading to the perception of a black color.

In summary, a solid substance that absorbs all wavelengths of visible light will appear black.
