What are examples of opaque objects?

An opaque object is an object that light cannot pass through. The light is either reflected, scattered or absorbed. The light is then converted to thermal energy.

The way that an object reflects light is divided into three groups: transparent, translucent and opaque. An example of an opaque object is an apple. When we look at an apple, the color reflected is red. This is because all of the other colors in the light spectrum are absorbed by the apple. When we see white objects, that means that all of the colors in the spectrum are reflected. Another example is wood. Wood stores the light that is collected. The thermal energy becomes fire.
