Step 1: Understand the definition of matter. Matter is anything that has mass and occupies space (has volume).
Step 2: Analyze each option to see if it fits the definition of matter:
Step 3: Water, copper, and air all have mass and take up space, so they are examples of matter.
Step 4: Light, however, does not have mass and does not occupy space in the traditional sense; it is a form of energy.
Step 5: Therefore, light is NOT an example of matter because it lacks mass and volume.
