Which statement correctly describes light?

• A. Light is a form of energy that you can see
• B. Light is a form of matter
• C. Light cannot travel through air
• D. Light is always visible and bright

Answer: (A)

The main idea here is that light is energy that our eyes can detect. Light behaves as energy that travels through air and even through empty space, and we perceive it when it reaches our eyes. It isn’t a form of matter, so claiming light is matter isn’t correct. Also, not all light is visible or bright—some light is outside the visible spectrum or can be very dim—so the statement that light is always visible and bright isn’t accurate. The best description is that light is a form of energy that you can see.
